Caitlyn O’Leary Books in Order (Updated April 16, 2026)

Caitlyn O’Leary’s backlist is easiest to understand in eras, not just in one long publication list. She starts with a few early romance and paranormal-leaning series, then settles into a long military romantic-suspense run built around Midnight Delta, Black Dawn, Night Storm, and Omega Sky, and then pivots into the newer small-town lane of Protectors of Jasper Creek.

She also has a handful of standalone or side-universe books that fit around those main tracks.

Quick answer

If you want the best first experience, start here:

1. Midnight Delta
2. Black Dawn
3. Night Storm
4. Night Storm Legacy
5. Omega Sky
6. Protectors of Jasper Creek

That order matches the broad progression Caitlyn O’Leary herself describes on her chronology page: she began Midnight Delta first, then Black Dawn, then Night Storm, and later Omega Sky. For most readers, that is more useful than trying to follow every timeline overlap.

Best place to start

1. Start with Her Vigilant SEAL if you want the series that sits closest to the center of Caitlyn O’Leary’s catalog. It is the cleanest entry into her military romantic-suspense style.
2. Start with His Wounded Heart if you want the newer small-town romantic-suspense books first.
3. Start with Trusting Chance / Theirs To Treasure only if you want to read absolutely everything from the beginning and do not mind starting with the older, more romance-forward material.

Early series and side books

Fate Harbor

1. Trusting Chance / Theirs To Treasure (2014): The series opener starts O’Leary’s backlist with a more romance-driven setup and is mainly for readers who want her earliest work.
2. Protecting Olivia (2014): This keeps the emotional, protective-romance pattern going while staying in the older style of the catalog.
3. Claiming Kara (2014): A reunion-focused entry that continues the same early contemporary-romance lane.
4. Isabella’s Submission (2014): This book keeps the series in the more intimate, relationship-first mode of O’Leary’s earliest publishing period.
5. Cherishing Brianna (2017): A later return that closes out the Fate Harbor set and reads best after the first four books.

Found

1. Revealed (2015): A kidnapped-heroine opener that blends romantic suspense with memory and identity questions, making it one of O’Leary’s clearer early suspense starts.
2. Forsaken (2015): The second book pushes harder on danger, family separation, and rescue.
3. Healed (2015): The trilogy closes with the strongest paranormal-leaning note, centering on healing and the threat that gift creates.

Shadow Alliance

1. Declan (2016): This introduces the Shadow Alliance concept through a former Army Ranger who creates a group to handle dark, off-the-books jobs.
2. Cooper’s Promise (2016): A short Shadow Alliance/Omega Team side entry, this works best as a companion piece rather than a major starting point.

Other early side books

1. Tempting Fire (2017): A Kindle Worlds novella about Chloe Avery and firefighter Zarek, later revised and expanded into Journey To Sunrise.
2. Protecting Hope (2016): A crossover-style standalone involving Wolf’s SEAL team and the Midnight Delta team during a rescue crisis.

The military romantic-suspense core

Midnight Delta

1. Her Vigilant SEAL (2015): The true foundation book for most readers, this launches O’Leary’s signature SEAL-driven romantic suspense.
2. Her Loyal SEAL (2015): The second book expands the team and confirms the series is meant to be read in sequence.
3. Her Adoring SEAL (2016): This deepens the emotional bonds within the Midnight Delta world while keeping the action-protection structure sharp.
4. SEALed with a Kiss (2016): A bridge-style entry that still belongs in the core run and is better read in place than skipped.
5. Her Daring SEAL (2016): The series grows more confident here, balancing mission pressure and relationship payoff.
6. Her Fierce SEAL (2016): Another solid team-centered installment that builds on the shared history established earlier.
7. A SEAL’s Vigilant Heart (2016): This companion-style title reinforces that the Midnight Delta books are cumulative, not purely isolated standalones.
8. Her Dominant SEAL (2017): By this stage the recurring cast is part of the main appeal, so order matters more.
9. Her Relentless SEAL (2017): This continues the military-protection rhythm with stronger late-series continuity.
10. Her Treasured SEAL (2017): A later core entry that rewards readers who have stayed with the team from the beginning.
11. Her Unbroken SEAL (2021): A long-gap return to Midnight Delta that reads best for established fans of the original series.
12. Her Forever SEAL (2026): Officially promoted as the finale of Midnight Delta, this is clearly a last-step book rather than a new entry point.

Black Dawn

1. Her Steadfast HERO (2017): The Black Dawn opener begins O’Leary’s next military-suspense branch with a disaster-and-rescue backdrop.
2. Her Devoted HERO (2017): The second book settles the series into a dependable hero-in-danger, heroine-in-danger, shared-mission rhythm.
3. Her Passionate Hero (2018): This builds on the same action-romance mix while strengthening the series’ internal continuity.
4. Her Wicked Hero (2018): A photograph-triggered connection and rising danger give this one a slightly sharper emotional hook.
5. Her Guarded Hero (2018): The team dynamic matters more here, making it smarter to read after the earlier books.
6. Her Captivated Hero (2018): Another late-middle entry where familiarity with the Black Dawn world adds weight to the romance.
7. Her Honorable Hero (2019): This revisits a couple shaped by earlier trauma and reads like a payoff novel for returning readers.
8. Her Loving Hero (2019): The final Black Dawn book closes the run with the strongest sense of accumulated series history.

Night Storm

1. Her Ruthless Protector (2019): This opens the Night Storm branch and shifts the catalog toward a newer team while keeping the same military-romantic-suspense DNA.
2. Her Tempting Protector (2020): The second book strengthens the team identity and confirms Night Storm as a full follow-on series, not a one-off.
3. Her Chosen Protector (2020): A pain-and-recovery centered story that keeps the branch emotionally intense.
4. Her Intense Protector (2021): This brings a fresh-start heroine into life-and-death trouble and fits the series’ increasingly polished formula.
5. Her Sensual Protector (2021): A later entry that continues the same rescue-heavy pattern while relying more on team familiarity.
6. Her Faithful Protector (2021): A kidnapped-students rescue mission gives this one one of the clearest external-action premises in the series.
7. Her Noble Protector (2021): By here, the Night Storm cast cohesion is part of the payoff.
8. Her Righteous Protector (2021): The eighth book closes the main Night Storm run and also helps point readers toward Omega Sky.

Night Storm Legacy

Lawson & Jill (2020): A one-book legacy offshoot focused on healing and emotional recovery, best read after at least part of Night Storm.

Omega Sky

1. Her Selfless Warrior (2022): This launches the next major SEAL-centered branch and is the best place to continue after Night Storm.
2. Her Unflinching Warrior (2022): A software-danger and forbidden-feelings setup keeps the series tight and fast-moving.
3. Her Wild Warrior (2022): This expands the line’s mission-homecoming energy and helps lock in the team identity.
4. Her Fearless Warrior (2023): A rescue-driven continuation that reads best after the first three books.
5. Her Defiant Warrior (2023): The fifth entry keeps the same protective intensity while leaning more heavily on the established cast.
6. Her Brave Warrior (2024): A “sleeping with the enemy” setup adds extra mistrust and tension to the now-familiar Omega Sky framework.
7. Her Eternal Warrior (2024): The current completed endpoint of Omega Sky closes the run with the strongest late-series continuity feel.

The small-town era

Long Road Home titles by Caitlyn O’Leary

This is a multi-author shared series, so these are best read as Caitlyn O’Leary contributions, not as a solo-author sequence.

1. Home Again (2021): O’Leary’s first Long Road Home entry brings a Navy veteran back to Jasper Creek to face old pain and a mystery from his past.
2. Defending Home (2022): A woman on the run, a baby in danger, and a reluctant hero make this one of her more direct suspense entries in the shared world.
3. Dreaming of Home (2024): This later contribution continues her Jasper Creek emotional-suspense lane inside the shared series.
4. Home At Last (2023): A return-and-healing story that fits naturally with her broader small-town phase.
5. Home of the Brave (2025): Officially described as a crossover between Long Road Home and Protectors of Jasper Creek, this is the key bridge book between her shared-world work and her own Jasper Creek series.

Protectors of Jasper Creek

1. His Wounded Heart (2023): The true starting point for O’Leary’s current small-town era, this opens Jasper Creek with healing, danger, and a more rooted community feel.
2. Her Hidden Smile (2024): The second book deepens the town and makes Jasper Creek feel like a long-term home base rather than just a setting.
3. Their Stormy Reunion (2025): A second-chance romance with stronger emotional history, this is where the series starts to feel fully settled.
4. Back To Our Beginning (2025): A return-to-first-love style entry that fits the series’ family-and-community-centered momentum.
5. A Tempting Seduction (2025): This continues the small-town suspense line while keeping the romance central.
6. Journey To Sunrise (2025): An expanded and updated version of Tempting Fire, this revisits Chloe and Zarek inside the Jasper Creek world.
7. Joy’s Homecoming (2025): A Jasper Creek retelling and expansion of Until Joy, this is the version to read if you want the story fully inside the series continuity.
8. Her Unending Horizon (2026): The eighth book keeps the Jasper Creek line moving into 2026 and signals that this is now O’Leary’s main active lane.
9. Her Unexpected Joy (2026): The current ninth book continues the small-town romantic-suspense run and is one of her newest announced releases.

Related standalone / parallel novel

Until Joy (2025): Originally published in Aurora Rose Reynolds’s “Until” world, this is best treated as parallel to Joy’s Homecoming rather than as a separate Jasper Creek mainline requirement.

Is there a chronological order?

Yes, but it is mostly for dedicated readers rather than newcomers.

Caitlyn O’Leary has an official chronology page and PDF timeline that place the books across overlapping series, and she explicitly notes the progression from Midnight Delta to Black Dawn to Night Storm to Omega Sky. For new readers, though, series order is still the better experience, because it preserves the growth of each team and keeps the emotional arcs cleaner.

Latest release status

As of April 16, 2026, the newest clearly listed Caitlyn O’Leary titles are:

• Her Unending Horizon – January 2026
• Her Forever SEAL – May 2026
• Her Unexpected Joy – June 2026

That makes Protectors of Jasper Creek and the final stretch of Midnight Delta the most current parts of her catalog.
