“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

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.
NATIONAL OUTDOOR BOOK AWARD WINNER

“The fact that McCulloch has actually climbed Manaslu allows her to ground her zippy thriller in first-hand experience. McCulloch knows what it’s like to be on a commercially guided ascent of an 8,000-meter peak. She knows what it’s like to be a relative novice in that context—surrounded by guides and Sherpas and other climbers who’ve got far more experience in the mountains. She knows what it’s like to be plopped down in a community of ambitious and sometimes disagreeable strangers in a setting that requires mutual trust. And she knows what it’s like to feel, as one of the few women on the mountain, like you’re ‘a target’ for misogyny and unwanted sexual advances. And so, in between the deaths and cliffhangers through which the plot hurtles, McCulloch puts her firsthand knowledge on display—in the process winning our trust as readers and shedding an uncomfortable amount of light on some of mountaineering’s less admirable aspects.”

“If you're looking for a book to thrill and transport you, then Breathless is the read for you! Set high in the chilling Death Zone, this thriller had me on the edge of my seat. I loved being immersed in the competitive, high-stakes world of alpine climbing, and Amy brilliantly evokes how risky this setting is, a setting that can only get deadlier with a murderer on the mountain . . . A must-read for 2022”

"Breathless is a high-altitude, high-stakes thriller that combines fascinating, authentic mountaineering experience with pure thriller entertainment.

—Matt Haig, #1 New York Times bestselling author of The Midnight Library
