Christi Caldwell Books in Order (Updated April 2, 2026)

Christi Caldwell writes interconnected Regency romance, but her catalog is best understood as a set of distinct series clusters rather than one single mandatory master sequence. Some readers will want the earliest books first. Most will do better by choosing a lane and staying inside that lane until the arc is finished.

That is the central rule for Christi Caldwell: read each series in order, but do not feel obliged to read the entire bibliography in publication order unless you want the full long-form evolution of her world.

First, choose your starting lane

1. Start with Forever Betrothed, Never the Bride if you want the earliest major entry point and want to see the long-running Regency catalog from near the beginning.
2. Start with In Need of a Knight if you want the biggest flagship line, because Heart of a Duke becomes one of the main pillars of Caldwell’s catalog and connects into later reading decisions.
3. Start with Wrath: The Devil Duke if you want the newest major active series and prefer entering through her current publishing direction.
4. Start with The Duke Alone if you want a more recent family saga entry point without committing immediately to one of the oldest, largest backlist series.

The simplest recommended reading approach

For most readers, this is the safest path:

1. Pick one series.
2. Read that series in exact book order.
3. Move to another series only after finishing the current one.

That matters because Caldwell’s books are romance-forward, but many series still build family networks, recurring side characters, and emotional callbacks that land better in order.

The big flagship series

Heart of a Duke

This is one of the clearest places to start if you want a central Christi Caldwell experience.

1. In Need of a Knight (2014): A prequel novella that opens the world and works best as the true beginning of the series.
2. For Love of the Duke (2014): The first full novel, establishing the series’ emotional style and aristocratic-family focus.
3. More Than a Duke (2015): Expands the series’ blend of rank, vulnerability, and second chances.
4. The Love of a Rogue (2015): Pushes the line toward a more openly rogue-centered romance dynamic.
5. Loved by a Duke (2015): Keeps the series rooted in wounded nobility and hard-won intimacy.
6. To Love a Lord (2015): Continues the family-and-society pattern with another emotionally burdened hero.
7. The Heart of a Scoundrel (2015): Leans into redemption and reputation, which become recurring Caldwell strengths.
8. To Wed His Christmas Lady (2015): A holiday entry that still belongs inside the main run rather than being treated as separate fluff.
9. To Trust a Rogue (2016): Builds on the series’ interest in damaged trust and earned devotion.
10. The Lure of a Rake (2016): Shifts toward a more temptation-driven romantic setup.
11. To Woo a Widow (2016): A widow-centered story that deepens the series’ emotional maturity.
12. To Redeem a Rake (2016): Another redemption-focused entry, very much in line with the title’s promise.
13. One Winter with a Baron (2016): A winter-set romance that still functions as core series reading.
14. To Enchant a Wicked Duke (2017): Pushes the series further into morally complicated aristocratic hero territory.
15. Beguiled by a Baron (2017): Continues the run with another deception-and-desire structure.
16. To Tempt a Scoundrel (2017): Keeps the series’ favorite tension between reputation and vulnerability alive.
17. To Hold a Lady’s Secret (2020): Returns to the world after a gap and is best read in series order rather than by date alone.
18. To Catch a Viscount (2022): Late-series entry that pays off better if you already know the surrounding world.
19. Defying the Duke (2022): Continues the final stretch with another duty-versus-desire conflict.
20. To Marry Her Marquess (2022): A late addition that works best after the earlier social and family context is already in place.
21. The Devil and the Debutante (2022): Moves the series into a sharper opposites-and-danger rhythm.
22. Devil by Daylight (2022): The current endpoint of the main sequence and best saved for last within the series.
23. My Heart Forever (2023): Listed separately on the site as a Halloween romance, but it sits in the wider Caldwell catalog and should be treated as optional rather than a new starting point.

The earlier foundation series

Scandalous Seasons

If you want Caldwell’s earliest major sequence, this is the place.

1. Forever Betrothed, Never the Bride (2013): The opening book and the clearest starting point for readers who want the earliest sustained series entry.
2. Never Courted, Suddenly Wed (2014): Continues the marriage-and-society complications established in book one.
3. Always Proper, Suddenly Scandalous (2014): Turns propriety into pressure and keeps the series’ title pattern fully intact.
4. Always a Rogue, Forever Her Love (2014): A more rogue-driven romance that still sits firmly in the same social world.
5. A Marquess for Christmas (2014): A seasonal entry that still belongs in sequence because it sits inside the series continuity.
6. Once a Wallflower, at Last His Love (2015): Brings the wallflower thread to the foreground and closes the original six-book run.
7. Endlessly Courted, Finally Loved (2023): A much later return to the series world, best read after the original run.
8. Once a Rake, Suddenly a Suitor (2023): Another later companion/extension title for readers already invested in the series setting.
9. Once Upon a Betrothal (2023): A final later-era add-on best treated as part of the extended series shelf, not an early entry point.

Mid-catalog historical romance lanes

Lords of Honor

1. Seduced by a Lady’s Heart (2015): Opens a military-tinged Regency romance line centered on returning men and emotionally guarded women.
2. Captivated by a Lady’s Charm (2015): Keeps the series intimate and character-driven rather than sprawling.
3. Rescued by a Lady’s Love (2016): Continues the rescue-and-healing pattern built into the series titles.
4. Tempted by a Lady’s Smile (2016): A lighter-sounding setup that still fits the same emotional register.
5. Courting Poppy Tidemore (2019): A later addition that lands best after the core run.

Heart of a Scandal

1. Schooling the Duke (2017): Opens the series with a corrective, oppositional setup between heroine and titled hero.
2. A Lady’s Guide to a Gentleman’s Heart (2018): Keeps the tone relationship-centered while broadening the social stakes.
3. A Matchmaker for a Marquess (2019): Pushes the series into more deliberate interpersonal meddling and emotional rearrangement.
4. His Duchess for a Day (2019): Leans into temporary roles and shifting status.
5. Five Days with a Duke (2020): Compresses the timeline and heightens emotional pressure.
6. Rogues Rush In (2020, related collection/duet placement): Commonly grouped with this world, but best treated as optional rather than essential core continuity.

Sinful Brides

1. The Rogue’s Wager (2016): Opens a tighter four-book series with a sharper gaming-and-risk flavor.
2. The Scoundrel’s Honor (2017): Continues the vice, reputation, and redemption themes.
3. The Lady’s Guard (2017): Shifts toward protection and loyalty while staying in the same emotional lane.
4. The Heiress’s Deception (2017): Closes the quartet with inheritance, secrecy, and trust at the center.

The Theodosia Sword

1. Only For His Lady (2016): Opens the series with a possession-and-devotion frame typical of Caldwell’s romantic tension.
2. The Theodosia Sword (2017): The central artifact/world hook becomes more important here.
3. Only For Her Honor (2017): Continues the linked romantic and honor-based stakes.
4. Only For Their Love (2017): Pays off the sequence and should be read last within the set.

Family, espionage, and crossover-rich lines

Brethren of the Lords

1. My Lady of Deception (2015): Opens the duo with secrecy and identity at the center.
2. Her Duke of Secrets (2018): Continues the clandestine mood and is best read after book one.

The Brethren

1. The Spy Who Seduced Her (2017): Launches the Home Office espionage-romance line with secrecy built directly into the premise.
2. The Lady Who Loved Him (2018): Continues the spy structure with a more intimate emotional focus.
3. The Rogue Who Rescued Her (2018): Brings danger and protection together in a more overt rescue arc.
4. The Minx Who Met Her Match (2019): Keeps the series lively while preserving the espionage-adjacent atmosphere.
5. The Spinster Who Saved a Scoundrel (2020): Closes the sequence by returning to Caldwell’s favorite redemption notes.

Lost Lords of London

1. In Bed with the Earl (2020): Opens a darker, more intimate mini-sequence around missing heirs and damaged aristocrats.
2. In the Dark with the Duke (2020): Continues the hidden-history tone with stronger gothic energy.
3. Undressed with the Marquess (2020): Finishes the trio and works best after the first two reveal the broader setup.

Newer and more current series

All the Duke’s Sins

This is one of the better modern entry points for readers who want a newer Caldwell run without starting at the very beginning of the bibliography.

1. It Had to Be the Duke (2021): Opens the series with Caldwell’s familiar collision of title, duty, and reluctant vulnerability.
2. Along Came a Lady (2021): Builds naturally on the tone and structure of book one.
3. One for My Baron (2022): Keeps the series rooted in romance first, with continuity best appreciated in order.
4. Desperately Seeking a Duchess (2022): Continues the run with a more openly searching, emotionally exposed setup.
5. The Diamond and the Duke (2024): Extends the series later and should be saved for after the first four.

Wantons of Waverton

1. Someone Wanton His Way Comes (2021): Opens a playful but still scandal-centered trilogy.
2. The Importance of Being Wanton (2021): Continues the witty title game with another reputation-driven romance.
3. A Wanton for All Seasons (2021): Closes the set with a seasonal capstone.

Scandalous Affairs

1. A Groom of Her Own (2021): Opens a later-era series with marriage and independence in the foreground.
2. Taming of the Beast (2021): Pushes harder into taming, resistance, and transformation.
3. My Fair Marchioness (2021): Uses makeover and status language in a classic romance framework.
4. It Happened One Winter (2021): A winter-set entry that remains part of the core sequence.
5. Loved and Found (2022): Finishes the line by combining reunion energy with emotional payoff.

The McQuoids of Mayfair / McQuoid Family Saga

This is one of the clearest current-family-saga lanes on Caldwell’s site.

1. The Duke Alone (2022): Opens the McQuoid sequence and introduces the family’s shipping-world backdrop.
2. The Heiress at Sea (2023): Expands the maritime family setting and pushes the series outward geographically.
3. A Sure Duke (2024): Continues the line and should be read after the first two.
4. While You Were Sailing (2025): A Christmas short novel set in the McQuoid family world, best read after the core run because it assumes interest in the family dynamics.
5. The Villain (2026): The newest confirmed McQuoid Family Saga release and the current latest major Christi Caldwell title.

Seven Deadly Sins

This is the newest major numbered sequence prominently featured on the site.

1. Wrath: The Devil Duke (2024): Opens the series with a sin-based branding that marks a more current Caldwell lane.
2. Lust: The Bad Earl (2024): Continues the sequence with another vice-driven aristocratic romance.
3. Pride: The Rogue (2024): Keeps the structure consistent while broadening the sinner lineup.
4. Sloth: The Fallen Earl (2025): Shifts the hook toward neglect, regret, and recovery.
5. Obsession: The Unspoken Sin (2025): Deepens the intensity and feels like the series tightening its grip.
6. Greed: The Savage (2025): Raises the acquisitive, dangerous edge of the concept.
7. Gluttony: The Dominant Sinner (2026): The officially listed series finale on the author’s coming-soon page.
8. Wolf of Mayfair (status listed on books page): Present on the site’s books page, but without the same clear release context in the official reading-order and publication-order pages, so it is safest to treat as listed but not yet cleanly slotted here.

Smaller early series

Danby

1. Winning a Lady’s Heart (2013): One of Caldwell’s earliest books and a useful historical marker for the backlist.
2. A Season of Hope (2013): Completes the short Danby sequence and is often grouped with her holiday-friendly earlier work.

What order matters most?

For Christi Caldwell, series order matters more than global order.

That is the decision that keeps the page manageable. Her bibliography is too large and too segmented for one universal reading order to be the only sensible recommendation. Readers usually get the best experience by choosing one of these routes:

• earliest Caldwell: Scandalous Seasons
• flagship long series: Heart of a Duke
• newer family saga: The McQuoids
• newest active major line: Seven Deadly Sins

Best starting points

• For the earliest series start: Forever Betrothed, Never the Bride
• For the biggest central series: In Need of a Knight
• For a newer family saga: The Duke Alone
• For the most current branded series: Wrath: The Devil Duke

Latest release status

The newest confirmed Christi Caldwell release I found on her official site is The Villain (2026), presented as an available-now McQuoid Family Saga title. Her official coming-soon page also lists Gluttony: The Dominant Sinner as a February 13, 2026 release and the finale of Seven Deadly Sins. That means the catalog is active, but The Villain is the safest “latest release” answer from the current site presentation.
