Hannah has been running from her demons ever since she emerged from a harrowing wilderness trip without her fiancé. No one knows exactly what happened the day Ben died, and Hannah would like to keep it that way... even if his ghost still haunts her with vivid waking nightmares that are ruining her life. So when her friend group gets an exclusive invitation to a restorative spiritual retreat in Joshua Tree, Hannah reluctantly agrees in search of a fresh start.
Despite her skepticism of the strange Guru Pax and his belief in the supernatural world, Hannah soon finds healing through all the yoga, sound baths, and hot springs offered at the tech-free haven. But this peaceful journey of self-discovery quickly descends into a violent fight for self-preservation when a mysterious killer starts picking off retreat attendees in increasingly gruesome ways. As the body count rises and Hannah’s sanity frays, she’ll have to confront her dark past and uncover the true nature of a ruthless monster hellbent on killing her vibe for good.
If you're a fan of slashers, unreliable narrators, and the kind of mystery that keeps you second-guessing —Breathe IN, Bleed Out is a wickedly fun ride. Brian McNulty delivers a fast-paced, genre-savvy novel that’s as much a love letter to horror tropes as it is a clever psychological mystery.
This book throws you into a world that feels like it was born out of a late-night horror movie marathon of Friday the 13th. You’ve got the tension between characters, the looming sense that someone (maybe everyone?) is hiding something, and the unreliability of the main character who is already seeing the ghost of her dead fiancĂ©.
The isolated setting adds so much creeping dread and the growing paranoia builds until you are yelling "The killer is right behind you!". Mix that with a little bit of gritty angst and dark humor. McNulty really leans into the “whodunit” energy while still delivering all the bloody, campy, adrenaline-pumping thrills you expect from a slasher.
If you’re a fan of books that keep you guessing and characters who keep you suspicious, Breathe IN, Bleed Out is well worth your time. What really sets this apart from your typical slasher is the way it messes with your head. It’s a bloody good time — in every sense.
