"What Stephen King did for an empty hotel in The Shining, Taylor Adams does for a treacherous cave in his bracing, breathtaking Her Last Breath."
—BookPage

From the bestselling author of No Exit and The Last Word comes a heart-pounding thriller that plunges readers into the suffocating darkness of a cave—and the even darker secrets that lie within.

When Tess reluctantly joins her adventurous best friend Allie on a caving expedition, she expects to confront her claustrophobia—not a stranger who traps her in a fight for her life. A man who claims to be a fellow caver harasses them at the cave's entrance. Confident, take-no-shit Allie insults the guy—and he retaliates. Soon, Tess is trapped inside a narrow crawl space hundreds of feet underground, fighting to stay alive.

Hours later, Tess emerges alive—but the nightmare is far from over.

As Tess recounts her harrowing story of survival, the detective interviewing her shares new and shocking secrets about Allie's true past. Together, they begin to suspect the brutal attack wasn't so random after all. In the hospital, as Tess pieces together the events with a detective, she learns shocking truths about Allie's past that reframe everything. Was the attack truly random? Who was Allie beneath her dazzling interior? And most chilling of all—has Tess really escaped the danger, or is it still closing in?
