AS SEEN ON THE TODAY SHOW • A high-altitude thriller that will take your breath away—Cecily Wong is on her most dangerous climb yet, miles above sea level. But the elements are nothing compared to one chilling truth: There's a killer on the mountain.

"A vertigo-inducing page-turner by an author who brings the high-stakes world of expert mountain-climbing to life on the page." —Nita Prose, #1 New York Times bestselling author of The Maid

Journalist Cecily Wong is in over her head. She's come to Manaslu, the eighth-highest peak in the world, to interview internationally famous mountaineer Charles McVeigh on the last leg of a record-breaking series of summits. She's given up everything for this story—her boyfriend, her life savings, the peace she's made with her climbing failures in the past—but it's a career-making opportunity. It could finally put her life back on track.

But when one climber dies in what everyone else assumes is a freak accident, she fears their expedition is in danger. And by the time a second climber dies, it's too late to turn back. Stranded on a mountain in one of the most remote regions of the world, she'll have to battle more than the elements in a harrowing fight for survival against a killer who is picking them off one by one.
