Verdict: An immersive, carefully built shape-shifter thriller with one of the most thought-through hidden societies in sapphic paranormal fiction, held back by a romance that only fully arrives in the last stretch of a very long book.
Best for: Readers who love worldbuilding, urban fantasy and a slow, earned connection, and who are happy for the love story to sit inside a suspense plot rather than lead it.
Heat level: ★★☆☆☆ (2/5 — one explicit scene, late)
Rating: ★★★★☆ (3.9/5 — a 4.16 Goodreads average across almost 3,000 ratings, docked for a romance that arrives very late)
Tropes: Enemies to lovers, assassin assigned to the target, hidden shifter society, slow burn, forced proximity, human and shifter, secret identity, morally grey heroine, found family, multiple POV.
Second Nature by Jae is the first book in her Shape-Shifter series, first published in 2009 and reissued by Ylva in a revised edition — a sapphic paranormal romance in which a reclusive novelist writes a shifter romance a little too close to the truth, and the hidden shifter society sends a soldier to stop the book by any means necessary.
It holds a 4.16 average across almost 3,000 Goodreads ratings, won several small-press awards in 2009 and 2010, and has found new life since Jae revived the series in 2025. Readers praise its world almost without exception. What divides them is how long they wait for the romance, and that is worth knowing before you start.
What Is Second Nature About?
Second Nature reads as urban fantasy and suspense as much as romance. Its centrepiece is the Wrasa, a secret society of shape-shifters living among humans, with its own laws, hierarchy and enforcers, and a scientific logic behind the shifting that readers find unusually convincing. The romance unfolds inside that world, against a plot about secrecy and survival.
Jorie Price is a reclusive human writer whose novel about shape-shifters threatens to expose the people she does not know are real. Griffin Westmore is a liger shifter and an elite Wrasa operative, sent to infiltrate Jorie’s life, stop the manuscript and, if it comes to it, eliminate her. The book moves between several points of view, including the antagonists’, which deepens the world but, for some readers, slows the central relationship.
What Makes This Sapphic Shifter Romance Work
- The worldbuilding: The most praised element by far. More than fifteen reviewers single out the Wrasa society and the research behind its shifter biology and animal behaviour.
- A slow burn with no instalove: Around eight readers praise how gradually the relationship is earned — the opposite of the instant mates common in shifter romance.
- Sensory detail: Several readers love how scent and instinct are used as a language of attraction.
- The characters: Jorie’s practical intelligence and Griffin’s dry humour, including her running battle with ordinary house cats, are recurring favourites.
- The audiobook: Abby Craden’s narration is widely praised — a strong option for sapphic shifter romance fans who listen.
Book Synopsis
Jorie Price writes paranormal romance, keeps to herself and has no idea how dangerous her latest manuscript is. Her book about shape-shifters is fiction to her. To the Wrasa — the shifters who have spent centuries hiding in plain sight — it reads like a breach of their most important secret.
Griffin Westmore is the operative they send to deal with it. She is a liger shifter and a disciplined soldier, used to orders that are simple even when they are ugly: get close to the writer, find out what she knows, stop the book from being published, and do whatever else is necessary. Posing as someone she is not, Griffin moves into Jorie’s world and begins to watch.
The closer she gets, the less simple her orders look. Jorie is not a threat; she is curious, funny and far more perceptive than Griffin expected, and every day undercover makes the job harder to finish. As others inside the Wrasa start to move against the writer, Griffin has to decide where her loyalty lies — to the society that made her, or to the human she was sent to silence.
My Review
The world is the triumph here. Jae built the Wrasa with real care — a society with its own rules, ranks and history, and shifting grounded in a biology that feels researched rather than hand-waved. Readers who usually bounce off paranormal romance because the worldbuilding feels thin consistently say this one won them over.
The relationship, when it comes, is the second strength. There is no instant fated-mates shortcut here: Griffin and Jorie have to learn each other, and trust has to be earned across a lie Griffin is living. The use of scent and instinct as a language between them is a lovely touch, and Griffin’s dry humour keeps the long book from getting heavy.
Where it struggles is pace, and this is the most repeated complaint rather than a stray one. Around seven readers say the romance is too slow and that the couple’s real time together is squeezed into the final fifth of the book. About five say the first half drags, and a few feel the antagonist chapters drain tension from the central relationship. A handful find the premise — killing a writer over a novel — hard to swallow, and a couple say the ending, with its time jump, comes too quickly. Several long-time Jae readers rank it below her contemporary romances.
One expectation to reset: it is sold as enemies-to-lovers paranormal romance, and LezReviewBooks described it as less of a romance than a thriller. Goodreads readers shelve it under fantasy before romance. If you came for heat and banter between rivals, calibrate; if you came for a deep, suspenseful world with a love story growing inside it, it delivers.
My honest note: A rich, patient urban fantasy whose romance arrives late but earns its ending. If you need the couple on the page early and often, this will test you. If you love a fully realised world, it is one of the best in sapphic shifter fiction.

How Spicy Is Second Nature?
A 2/5. I could not get a romance.io reading for this title, so the number comes from readers: one Goodreads reviewer describes a single explicit sex scene near the end, StoryGraph reviewers call the intimate content very light and reserved for the final chapters, and LezReviewBooks noted the book’s focus on action and tension rather than intimate scenes. When it arrives it is on the page; it just arrives very late.
No reviewer I found flags kink content. If you want a shifter romance at a similar low temperature, The Lone Wolf Café sits in the mild band; She Came for the Pack is the opposite end of the scale.
Who Should Read This Book?
You’ll likely love it if: you love detailed worldbuilding, you prefer an earned slow burn to instant mates, you enjoy suspense and urban fantasy, and long books feel like an invitation rather than a chore.
You may want to skip it if: you want the romance on the page from early on, slow first halves lose you, you want real heat, or multiple villain points of view frustrate you.
In short: a deep, suspenseful shifter world with a romance that takes its time to bloom.
What Readers Are Actually Saying (October 2026)
The story of this book is longevity. First published in 2009, it won the Golden Crown Literary Society award and placed in the Rainbow Awards the following year, and it has kept finding readers ever since — helped by Ylva’s revised edition, a 2020 audiobook and, most recently, Jae’s return to the series in 2025 with two new novels that rate even higher. The numbers: a 4.16 average across almost 3,000 Goodreads ratings, 3.98 across 119 StoryGraph reviews with a 2% did-not-finish rate, and 4.5 from almost 1,200 Amazon ratings. I found no trade reviews and no Reddit or BookTok conversation driving it. The audiobook, narrated by Abby Craden for Tantor, runs about 13 hours 39 minutes, and listeners consistently praise her.

Why readers love it (according to the discourse): The worldbuilding, first and by a wide margin — more than fifteen readers single out the Wrasa and the science behind the shifting. Then the slow burn: about eight praise a relationship with no instalove. A handful love the sensory detail and Griffin’s humour, and several listeners rave about Craden’s narration. The minority who rate it lower still tend to praise the world.
What readers argue about and complain about: Pace, above everything. About seven readers say the romance arrives only in the last fifth of the book and the couple shares too little page time; around five say the first half plods. A few feel the antagonists’ chapters dilute the central story. Smaller notes: the premise of killing a writer over a novel strains belief for a couple of readers, the ending’s time jump feels abrupt to a couple more, and three or four Jae fans say it is not her best. Only about 4% of Goodreads ratings are one or two stars, so even the critics mostly land at three.
The series question everyone should ask first: this book completes Jorie and Griffin’s story without a cliffhanger, and their life together continues in the short-story collection Natural Family Disasters. The other Shape-Shifter novels follow different couples, and the 2025 books, Enemies by Nature and Shifting Nature, are rated higher than this one. If the assassin-and-target setup was the draw, Requiem for Immortals is the book readers compare it to.

If You Loved Second Nature, Read These Next
Readers comparing this to other dangerous romances land on Requiem for Immortals, which builds its love story between an assassin and her target. If it was the shifters you loved, The Last Caspian offers another sapphic paranormal world with open-door heat. And for a cozier take on shifters with a lighter touch, The Lone Wolf Café is a gentle contrast.

The Bottom Line
Second Nature is a book whose world is bigger than its romance. The Wrasa is a superbly imagined society, the slow burn is honest, and the suspense keeps the pages turning. It is also long, slow to start, and stingy with the couple’s time together until the final stretch. If you love immersive worldbuilding and do not mind waiting for the love story, it is a classic of sapphic paranormal fiction for good reason. Check Second Nature on Amazon →
The Eikna Overall Ranking
On the Eikna scale, Second Nature ranks as an award-winning, long-lived sapphic shifter novel — richly imagined, suspenseful and patiently romantic, held back by a slow pace and a late-arriving love story, and best approached as urban fantasy with a romance rather than a romance first.
