“I climbed Manaslu with Amy. She's a pro." — Nirmal Purja, author of The Outer Limits and star of the Netflix documentary 14 Summits “If you're looking for a book that will leave you in awe, you've found it! The action takes place in a chilling death zone. I was sitting on the edge of my chair. I loved being immersed in the high-stakes world of mountaineering. Amy brilliantly shows how dangerous this environment is, an environment that could become even more deadly... A must read." — Sarah Pearce, bestselling author of Sanatorium “The fact that McCulloch actually climbed Manaslu allows her to base her thriller on personal experience. McCulloch knows what it's like to make a commercial ascent of an 8,000-meter peak. She knows what it's like to be a beginner surrounded by guides, sherpas and more experienced climbers. She knows what it's like to be in the company of ambitious and sometimes unpleasant strangers. In an environment that requires mutual trust. And she knows what it's like to be one of the few women on the mountain, to feel like a target for misogyny and unwanted sexual advances. And so, in between the deaths and the plot's obstacles, McCulloch demonstrates his first-hand knowledge—in the process, earning our trust as readers and shining an uncomfortable light on the less wonderful aspects of mountaineering." — Climbing.com
