To The Bone Review (Kylie Cross): Is It Worth Reading?

Updated on October 8, 2026

Verdict: A sapphic why-choose with a strong revenge premise — a sorority of women who go after men who hurt women — and far more sex than romance, held back by rough editing, a heroine who is aroused on almost every page and a cliffhanger that leaves most of its mystery unsolved.

Best for: Readers who want a very explicit F/F/F/NB why-choose with a secret-society plot, feminine rage, a hostile love interest and a series they will binge straight through.

Heat level: ★★★★★ (5/5 — romance.io’s small sample says 5, “explicit and plentiful”; two readers count nine spicy scenes, with toys, group scenes and light BDSM)

Rating: ★★★½☆ (3.5/5 — a 4.13 Goodreads average from 746 ratings, adjusted for recurring complaints about editing, thin relationship development and an unresolved ending)

Tropes: Why choose (F/F/F/NB), sorority and secret society, revenge on abusive men, framed for murder, hostile love interest, enemies to lovers, college setting, series opener.

To The Bone is the first book in Kylie Cross’s Killer Queens trilogy, a dark sapphic romance self-published in November 2024. Its narrator, Elle, enrols at Atwood University after a year away following an assault, and finds that the man who hurt her is still there — and that three members of a secretive sorority have been quietly watching over her.

It has 746 Goodreads ratings averaging 4.13 and 98 written reviews, 472 Amazon ratings averaging 4.4, and a 4.30 from five romance.io readers. Three in four Goodreads readers give it four or five stars. The reviews split in a way that is easy to predict once you know what the book is: readers who came for heat and a cult-like revenge plot love it, and readers who came for a love story say there is not much of one yet.

What Is To The Bone About?

The author describes it as a dark, sapphic, new adult, why-choose (f/f/f/x) university bully romance, and asks readers to check the content warnings in the author’s note. In practice it is a campus revenge thriller with a lot of sex. Readers list sororities, secret societies, forced proximity, enemies to lovers, light BDSM and revenge on men who target women. The romance.io community tags it poly, reverse harem, FFF+, bdsm and cliffhanger.

The “x” matters. Elle’s three love interests are Teresa, a hacker who seems to know everything about her; Kennedy, a charmer who uses they/them pronouns; and Xander, the group’s leader, who appears to want Elle dead. Readers describe the pairing as F/F/F/NB. It is told mostly in Elle’s first-person point of view, with a small number of chapters from the others.

What Makes This Dark Why-Choose Romance Work

The premise: A sorority of women taking justice into their own hands against men who hurt women is the hook readers mention first, and two reviewers name its feminine rage as the draw.
The cult: Even a two-star reviewer says the sorority’s cult tactics are well presented. The Laniidae sisters are the most interesting thing in the book.
The mystery: One fan says each chapter adds a puzzle piece and opens more questions, and others say the tension kept them reading in one sitting.
The heat: Readers who wanted a spicy sapphic why-choose say they got one. Two count nine scenes across 482 pages.
The binge factor: Several fans describe reading it in one sitting and going straight to book two, and one is on her third read.

Book Synopsis

Elle has spent a year putting her life back together after an assault. Atwood University is meant to be a fresh start, but her attacker has not finished with her, and the fraternity he belongs to is making her life on campus dangerous. Then his efforts to ruin her begin to fail, as if someone is undoing them.

That someone is three people. When a fraternity brother disappears and the blame lands on Elle, the women of the Laniidae sorority step out of the shadows and offer her protection — on the condition of total loyalty. Teresa knows her secrets. Kennedy can talk their way out of anything. Xander, who runs the group, treats Elle with open hostility and is keeping a secret that involves her.

Elle has no reason to trust any of them, every reason to want what they are offering, and a name to clear before the frame-up sticks.

My Review

What works here is the idea. A sorority that recruits wronged women and turns them into a weapon against the men who hurt them is a strong engine for a dark romance, and Cross commits to it. The secret-society rituals, the loyalty tests and the sense that Elle has joined something cult-like give the book its best pages, and readers who rated it highly almost all mention the plot before the romance.

Where it struggles is the love story. The single most repeated criticism in the reviews is that the relationships run on lust rather than connection: readers describe a heroine who throbs or aches at the sight of any of the three, so often that several started counting. Even generous three-star reviews say they finished knowing little about the characters. The attention is also uneven. Elle and Teresa get most of the development, while Kennedy and Xander stay a slow burn, which bothers readers who want a why-choose to give each pairing its due.

The second complaint is editing. At least four reviewers flag typos, grammatical errors and awkward sentences, and one says it needed another round or two of rigorous editing. The third is the ending: the book runs to 482 pages and leaves most of its questions open. One reviewer estimates that 90% of the mystery goes unanswered, and others call the final pages a cliffhanger that feels like the middle of a book.

The darkness deserves a plain warning. Elle’s backstory is an assault, Xander’s hostility drives much of the tension, and one critical reviewer says she was not prepared by the content warnings or the synopsis for Elle to be physically assaulted by a love interest; she also questions how one scene handles consent. The author does publish a content note, and readers repeatedly advise checking it first.

My honest note: An addictive, extremely explicit revenge plot for readers who want a sorority of dangerous women and plenty of sex, and a frustrating one for readers who want four people to fall in love on the page. Go in expecting part one of three.

How Dark and Spicy Is To The Bone?

A 5/5 on heat, and here the sources agree. Romance.io rates it five of five, “explicit and plentiful,” though only five people have voted. Readers back that up in their own words: two separately count nine spicy scenes, others list group scenes, toys and light BDSM, and one calls it the freakiest book they have read. Some readers rate the spice at four chillies, but no one describes it as restrained. A frequent complaint is simply that there is too much of it for the romance underneath.

On darkness, it sits in the upper middle of the range. The assault backstory, a vigilante sorority and a love interest who is openly hostile set the tone, and the reviewer who flagged on-page violence from a love interest is a reminder to read the content note. It is closer in register to Don’t Hate Me than to the most brutal books on our list, such as Collateral Damage or Merciless Queen.

Who Should Read This Book?

You’ll likely love it if: you want a very spicy sapphic why-choose, a revenge plot about women turning on the men who hurt them, a secret society with a cult edge, and a series to binge in Kindle Unlimited.

You may want to skip it if: you need emotional development before the sex, typos pull you out of a book, violence from a love interest is a hard limit, you want every pairing in a why-choose to get equal time, or you hate cliffhangers.

In short: a plot-and-heat dark romance first and a love story second.

What Readers Are Actually Saying (October 2026)

This is a steady indie seller with a loyal audience. It came out in November 2024, it is in Kindle Unlimited, and it has 746 Goodreads ratings and 98 written reviews. The distribution is 45% five stars, 30% four, 16% three, 4% two and 2% one. Amazon readers are kinder: 88% of its 472 ratings are four or five stars. We found no audiobook edition on Amazon or Libro.fm.

Why readers love it (according to the discourse): The premise, first — “badass sorority girls out for revenge” is how one reader sums it up. The mystery and the sense of being inside a cult are the second draw, and the heat is the third. Fans call it addictive, and two say it was even better on a reread.

What readers argue about and complain about: Lust over romance is the biggest complaint, raised in three-star reviews as well as two-star ones. Editing is second. The heroine is third: readers find Elle’s constant arousal cartoonish, and some are not sure they like her. Two reviewers stopped early, at 30% and 64%, and one of them compares it to Tricky Girls as another why-choose that did not work for her. A smaller group objects to the treatment of consent and violence.

The series question everyone should ask first: To The Bone does not stand alone. Readers call the ending a cliffhanger and say most of the mystery is held back. The good news is that the trilogy is complete: To The Flame and To The Grave are both out and in Kindle Unlimited. One reader who read Cross’s later Road to Ruin first says this series is wilder and more cult-like than that one.

The Bottom Line

To The Bone puts a sorority of vengeful women at the centre of a sapphic why-choose, and for readers who want plot and heat it works. It succeeds on its premise, its secret-society atmosphere, a mystery that keeps pages turning and spice that delivers everything the label promises. It is weaker on the relationships, which run on attraction more than connection, on editing that many reviewers notice, and on a long first book that answers very little. With the trilogy complete and in Kindle Unlimited, it is an easy pick for readers who want a dark, explicit binge and a harder sell for anyone looking for romance first.
