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.
