The Four (Layla Frost) Books in Order

The Four series by Layla Frost blends modern life with myth and magic, following four cursed siblings as they claw their way back to each other. If you like your romance tangled up with haunted houses, soul-stealing villains, and snarky banter, this is where to dive in.

Everything starts with Styx, told from the point of view of a woman who has always felt wrong-footed in her own life. After inheriting her grandmother’s house, she expects a quiet reset. Instead she finds con artists, odd coincidences, and a home that very much does not want to behave. The “ghost” in her spare room is not actually a ghost, the strange pull she feels is not just attraction, and the sense that fate has it out for her turns out to be literal.

As the series unfolds through Stoned, Broken, and Bones, the bigger picture comes into focus. The four main heroes are siblings who were bound up in a magical war and then scattered, their memories fractured. Each book pairs one of them with a different partner, and each relationship unlocks another piece of what was done to them. The romances are full, central arcs, but they also serve as a way to explore power, identity, and what it means to be seen when you are not entirely human.

Frost keeps the tone grounded even when the stakes go cosmic. The settings are recognizably modern, filled with bad first dates, pop culture references, and the everyday grind of work, bills, and family drama. Against that backdrop, demons, witches, and secret organizations feel less like distant monsters and more like the exaggerated version of the problems we all dodge. The humor and heat stop the darker moments from swallowing the story.

A big part of the draw is the found family element. By the time you reach Broken and Bones, the web of friends, lovers, and allies feels lived in and messy in the best way. People fight, forgive, and show up again when it matters. The siblings may be magically connected, but the series keeps reminding you that chosen bonds can be just as strong as those written in prophecy.

Throughout, the books lean into fated-mates romance. Each couple is drawn together by something bigger than either of them, yet Frost still gives them room to decide how that bond will work in practice. Consent, communication, and trust are treated as real work, even when destiny has already tied the knot. It makes the magic feel earned rather than automatic.

If you read in order, you will get a clear escalation from eerie house story to full-on war for souls. The Four is a good bridge if you already enjoy Frost’s contemporary books and want to test the waters of romantasy without leaving her voice behind.
