Endless ice. Thin air. The threat of dropping into nothingness thousands of feet below. This is the climb Silvia Vasquez-Lavado braves in her page-turning, pulse-raising memoir chronicling her journey to Mount Everest.

A Latina hero in the elite macho tech world of Silicon Valley, privately, she was hanging by a thread. Deep in the throes of alcoholism, hiding her sexuality from her family, and repressing the abuse she’d suffered as a child, she started climbing. Something about the brute force required for the ascent―the risk and spirit and sheer size of the mountains and death’s close proximity―woke her up. She then took her biggest pain as a survivor to the biggest mountain: Everest.
