A young woman's once-in-lifetime adventure in the world of extreme-altitude mountaineering takes a chilling turn when a series of deaths can no longer be written off as accidents. When journalist and novice climber Cecily Wong is asked to summit Mount Manaslu, the eighth-highest peak in the world, it's a career-making opportunity. She's been personally invited by Charles McVeigh, one of the most acclaimed mountaineers in the world, who wants her to report on the final leg of his record-breaking series of summits. But there's one caveat: he won't give her the interview until she's scaled the mountain as part of his climbing party. Cecily is by far the least experienced of the group, but she is intent on proving herself and will stop at nothing to reach the summit. But when strange things start to happen around her, she becomes concerned. And then people start to die. Stranded on the mountain with a team she barely knows, she must battle more than the elements in an epic fight for survival--against one of the world's most dangerous mountains and against an unknown assailant who is picking climbers off one by one.
