Kalynn Bayron Books in Order (Updated March 7, 2026)

Kalynn Bayron does not have one single long-running universe that everything feeds into. Her bibliography is easier to use if you split it three ways: a two-book YA fantasy sequence, a group of standalone YA novels and retellings, and a middle grade vampire series.

That matters because only a few of her books truly require sequence reading. Most of the rest can be chosen by mood.

The reading map

1. If you want the one place where order matters most, go to This Poison Heart and read the duology straight through.
2. If you want a single-book entry point, choose one of the standalones: Cinderella Is Dead, My Dear Henry, You’re Not Supposed to Die Tonight, Sleep Like Death, or Make Me a Monster.
3. If you are reading for a younger audience, start with The Vanquishers and stay in that series order.

Publication order

1. Cinderella Is Dead (2020): Two hundred years after Cinderella’s story was turned into royal law, Sophia runs from the kingdom’s marriage system and uncovers the truth buried under the fairy tale.
2. This Poison Heart (2021): Briseis, a girl with a dangerous gift for growing plants, inherits a mysterious estate and gets pulled into family secrets, poisonous magic, and Greek-myth roots.
3. This Wicked Fate (2022): Briseis’s story continues as the first book’s inheritance mystery turns into a wider struggle over legacy, power, and survival.
4. My Dear Henry: A Jekyll & Hyde Remix (2023): In Victorian London, Gabriel Utterson searches for the truth behind Henry Jekyll’s disappearance, turning the classic source text into a gothic queer mystery.
5. You’re Not Supposed to Die Tonight (2023): At a horror-themed camp where staged scares are part of the job, Charity discovers that one night’s performance has turned into the real thing.
6. The Vanquishers (2023): In Bayron’s middle grade vampire series opener, Boog and her friends learn the undead are not as gone as everyone thought, and that puts their town back in danger.
7. The Vanquishers: Secret of the Reaping (2024): The series expands the threat as Boog and the Squad face the consequences of the vampires’ return and start learning how much larger the fight really is.
8. Sleep Like Death (2024): Set in the same fairy-tale realm as Cinderella Is Dead, this Snow White–leaning companion follows Princess Eve as family secrets and a magical threat force her to question everything she has been taught.
9. Make Me a Monster (2025): Bayron’s Frankenstein-inflected YA horror follows Meka, a mortician’s assistant whose grief, love, and family business pull her toward resurrection and its cost.

The books that actually need an order

This Poison Heart duology

1. This Poison Heart: The setup book that introduces Briseis, the estate, the family mystery, and the mythology-driven stakes.
2. This Wicked Fate: The direct continuation, with no good reason to postpone it once you finish book one.

This is the clearest “read in order” lane in Bayron’s YA catalog. Start anywhere else only if you are not looking for a two-book commitment.

The Vanquishers series

1. The Vanquishers: The worldbuilding book, where Boog discovers the old vampire history is not as settled as adults claim.
2. The Vanquishers: Secret of the Reaping: The middle book that widens the conflict and deepens the threat.
3. The Vanquishers: Book 3: The still-unreleased conclusion, positioned by Bayron’s site as the final stand against the undead.

For middle grade readers, this is the strongest straight-line reading order in her bibliography.

The “same world, but not the same series” question

This is where readers can overcomplicate things.

Sleep Like Death returns to the fairy-tale realm of Cinderella Is Dead, but it is not presented as “Cinderella Is Dead Book 2” in the same simple sequel sense as This Wicked Fate follows This Poison Heart. It is better treated as a companion in the same story-world. You can technically read it on its own, but Cinderella Is Dead still makes the better entry point.

Best starting points by taste

1. Choose Cinderella Is Dead if you want the cleanest first Bayron novel. It is still the most obvious entry for readers who want her fairy-tale retelling side.
2. Choose This Poison Heart if you want the only current YA duology and you already know you want connected books rather than standalones.
3. Choose You’re Not Supposed to Die Tonight if you want a one-book horror read.
4. Choose The Vanquishers if you are shopping for middle grade first.
5. Choose Make Me a Monster if the appeal is her newer horror-romance direction rather than fantasy retellings.

Recommended reading order for most readers

A practical first-time route looks like this:

1. Cinderella Is Dead
2. Sleep Like Death
3. This Poison Heart
4. This Wicked Fate
5. My Dear Henry
6. You’re Not Supposed to Die Tonight
7. Make Me a Monster
8. The Vanquishers
9. The Vanquishers: Secret of the Reaping

That order is not pretending everything belongs to one continuity. It simply keeps the companion-world books together, preserves the one true duology, and then lets the standalones and middle grade books fall into a cleaner path.

Optional and separate-format books

Optional anthologies and short fiction

Bayron has also contributed to anthology and short-fiction spaces, but those are not central to understanding her main reading order.

Separate-format / franchise work

A Lost Revenge is Bayron’s original graphic novel in the Descendants universe. It belongs in a separate bucket from her original YA and middle grade fiction, because it is franchise tie-in work rather than part of her own ongoing continuity.

Latest release status

The latest full Kalynn Bayron novel currently out is Make Me a Monster.

Looking ahead, her official site also lists Tell the Ghosts I’m Gone for September 1, 2026, and it continues to point to a third Vanquishers book as the concluding volume of that series.

FAQs

What Kalynn Bayron book should I read first?

For most readers, Cinderella Is Dead is the simplest first pick. It is standalone-friendly, representative of her style, and still one of the easiest entry points.

That is the best approach. They share a fairy-tale world, and Cinderella Is Dead is the cleaner introduction.

Yes. Read This Poison Heart first.

Final recommendation
