Deiri Di Books in Order (Updated March 25, 2026)

Deiri Di writes science-fiction romance, alien romance, monster romance, and shifter romance, with most books grouped into clearly named series rather than one tightly shared continuity.

That means the best reading order is usually simple: pick a series, read it in publication order, and only jump between lanes when you want a different trope mix.

Quick answer

For most readers, the cleanest place to start is Cryo Crisis if you want a longer alien-romance run, Wild Mars if you want knotty shifter romance, or Scifi Alien Human Romance if you want a shorter modern entry point. Deiri Di’s series are mostly best treated as separate continuities, so there is no strong reason to read the entire catalog in one chronological sweep.

Where to start, depending on what you want

1. Start with Cryo Crisis if you want the biggest early Deiri Di series and a straightforward publication order.
2. Start with Wild Mars if you want a compact shifter sequence with a more feral tone.
3. Start with Alien Song if you want a shorter, newer alien-human romance line.
4. Start with Smutt Books Short Alien Romance only if you already know you want rapid, trope-driven short reads.

Cryo Crisis

This is one of the main Deiri Di entry points and still the easiest long series to follow cleanly.

1. Taken by the Alien Prince (2020): The series opener introduces the core Cryo Crisis setup, pairing stranded or vulnerable human stakes with a strongly possessive alien romance dynamic.
2. Rescued by the Warrior (2020): A rescue-focused second book deepens the protective tone and keeps the alien-human pairing style consistent.
3. Protected by the Warrior (2020): Protection becomes the central emotional engine, pushing the series further into safety, dependence, and trust.
4. Claimed by the Bodyguard (2020): A bodyguard structure adds closer forced proximity and a more openly possessive romantic setup.
5. Courted by the Alien Agent (2020): This entry shifts toward a more deliberate pursuit romance while staying inside the same broad alien world.
6. Tempted by the Alien Pilot (2020): The pilot angle gives the series a more mobile, adventurous feel without changing its basic romantic formula.
7. Tamed by the Warrior (2020): A more volatile connection sits at the center here, with taming and surrender shaping the emotional arc.
8. Craved by the Alien Botanist (2020): This book softens the job-title framing while keeping the familiar possessive and fated-feeling attraction.
9. Claimed by the Alien Prince (2020): A prince-centered closer returns the series to one of its strongest recurring power-and-devotion patterns.

Best way to read it

Read the whole series in publication order. This is the strongest “start here and keep going” lane in Deiri Di’s early catalog.

---

Wild Mars

This is Deiri Di’s core early shifter series and one of the most obvious alternatives to Cryo Crisis.

1. Wild Alpha (2020): The opener establishes the series’ raw shifter tone, with hierarchy, instinct, and control issues driving the romance.
2. Wild Omega (2020): The second book leans harder into pack and mating dynamics, deepening the biological and emotional pull.
3. Wild Beast (2020): This entry heightens the feral energy and makes the world feel more dangerous and physically intense.
4. Wild Wolf (2021): The series closes on a more personal and pack-rooted note, using loss, return, and recognition to deliver its payoff.

Why readers start here

Choose this series if you want Deiri Di at her most shifter-forward rather than her most alien-forward.

---

Haven for the Lost

A shorter two-book science-fiction romance series that works well for readers who want a compact read.

1. Unspoken (2020): A telepathy-centered setup gives this book a stronger communication barrier than most of Deiri Di’s more physically immediate romances.
2. Unseen (2021): The sequel continues the emotional and psychological emphasis, making this pair feel slightly quieter and more intimate than the author’s bigger alien series.

Reading note

Because it is only two books, this is one of the easiest Deiri Di series to try without committing to a long run.

---

Breeding Alien Prince

This is currently a one-book series branch.

His Fertile Prize (2020): A possessive alien-prince romance that builds around reproduction stakes and a more overtly primal claim dynamic.

Reading note

Treat this as a standalone until the series grows further.

---

Cryo Crisis Homeworld

This is a follow-on alien-romance lane that shares the Cryo Crisis naming but is its own separate numbered sequence.

1. Taken by the Beast (2021): The opener shifts the Cryo Crisis world toward a more creature-heavy and instinct-driven romantic setup.
2. Tamed by the Cowboy (2021): A cowboy-coded alien hero changes the flavor of the series without losing the possessive sci-fi core.
3. Seized by the Guard (2021): A guard-centered romance brings captivity, security, and watchfulness to the front.
4. Captured by the Pirate (2021): This entry adds a rougher adventure edge and gives the series one of its most overtly dangerous pairings.
5. Ordered by the Aristocrat (2022): The series closes with a more status-driven alien romance, using class and command to shape the tension.

Should you read this after Cryo Crisis?

Yes. Even though it is its own sequence, it makes the most sense after the main Cryo Crisis run.

---

Wild Mars Wild Pack

This is a later Wild Mars branch and is best treated as a companion or spinoff rather than the first stop.

1. Wild Pack (2023): The series opens by widening the Wild Mars concept from individual shifter romances to a more group-centered pack structure.
2. Wild Boss (2023): A leadership dynamic takes over here, giving the romance a more territorial and dominance-heavy feel.
3. Wild Prey (2023): Prey-and-pursuit energy becomes the hook, making this one especially direct in its power-play setup.
4. Wild Olympian (2023): The final book brings a more specialized hero identity into the pack framework and rounds out the branch.

Reading note

Read the original Wild Mars first. This branch will land better once you already know the broader shifter tone.

---

Cryo Crisis Possessive Predator

This is currently a one-book offshoot.

Alien Zoo (2023): A more high-concept Cryo Crisis spinoff that emphasizes captivity, danger, and predator energy more heavily than the main sequence.

Reading note

Best read after Cryo Crisis, since the title and branding clearly position it as a related branch.

---

Scifi Alien Human Romance

This is one of the easiest modern Deiri Di series to recommend because it is short, current, and very clear.

1. Alien Song (2024): The opener uses communication and cultural difference as the route into its alien-human romance.
2. Alien Dance (2024): The second book builds on the same alien-human pairing style with a more performative and chemistry-forward setup.
3. Alien Bride (2024): Marriage becomes the central structure here, giving the trilogy a more settled and committed ending.

Best use of this series

This is a strong choice if you want a newer Deiri Di series without committing to a huge backlist.

---

Chaos God Companion

This is a separate collaborative branch.

1. This Will Be Over Soon (2024, with Ariana Irendale): A companion novella that sits outside Deiri Di’s main alien and shifter lanes and works best as a side read for readers already interested in that world.

Reading note

Because it is a companion title and a collaboration, it is not a core starting point for a general Deiri Di reading order.

---

Chaos God Sugar and Spice Companion Shorts

These are companion shorts, not the backbone of the catalog.

1. Hard As Cake (2025): A short companion piece that adds flavor to the Chaos God corner rather than opening a major new storyline.
2. Small as a Mushroom (2025): Another brief side story that leans into the playful, extra-material feel of the companion line.
3. Dry as a Fish (2025): A further short installment that continues the supplemental pattern.
4. Cruel As A Tree (2025): This entry keeps the same companion-short function, expanding mood more than continuity.
5. Soft as a Spike (2026): The newest listed short continues the sequence without changing its optional status.

Reading note

Read these only if you are already following the companion material. They are not essential entry books.

---

Smutt Books Short Alien Romance

This is Deiri Di’s fastest-moving current series and the one most clearly built around short, trope-first reads.

1. Contract to Mate (2025): The series opens with an agreement-based mating setup that announces the line’s quick, high-concept approach.
2. Mated to the Monster (2025): Monster romance takes center stage here, leaning into instinct, size, and possession.
3. Fated to Mate (2025): A fate-bond angle gives the series one of its most classic paranormal-romance hooks.
4. Small Town Holiday Mate (2025): This book blends alien mating tropes with a seasonal small-town wrapper for a more playful variation.
5. Fifty Shades of Dragon (2025): Dragon energy shifts the series away from pure alien pairing while keeping the short, intense structure intact.
6. Forced Proximity Space Cruise (2026): A cruise setting and close quarters create the most obvious forced-proximity hook in the line so far.
7. Age Gap Space Cruise (2026): The age-gap trope becomes the main selling point while the series continues its rapid-release pace.
8. Single Dad Space Cruise (2026): A parental angle adds a different emotional texture to the same compact sci-fi-romance framework.
9. Enemies to Lovers Space Cruise (2026): This entry turns conflict into the central engine, making it one of the clearest trope-title books in the series.
10. Size Difference Space Cruise (2026): Physical contrast becomes the headline hook, matching the line’s overt trope-forward branding.
11. Pick Me Space Cruise (2026): The next listed installment appears set to continue the same short, themed cruise sub-run.

Best way to approach it

Read these in order if you want the full series, but this is also the easiest Deiri Di lane to sample by trope.

Contributed title

A Heart for a Scoundral (2024): A contributed story in the Alien Love Encounters project, best treated as a standalone anthology piece rather than part of Deiri Di’s core reading order.

Do you need a full chronological order across every series?

Not really. Deiri Di’s catalog is more useful when separated by series than when blended into one giant timeline. The only places where order matters strongly beyond a single series are the obvious branch relationships, especially Cryo Crisis before Cryo Crisis Homeworld and Wild Mars before Wild Mars Wild Pack.

The most active current Deiri Di line is Smutt Books Short Alien Romance, with several 2025 and 2026 entries listed in sequence and Pick Me Space Cruise shown as the next upcoming book. The newest companion short listed is Soft as a Spike (2026).
