"An exhilarating adventure."—Zoje Stage, USA Today bestselling author of Baby Teeth and Dear Hanna

"Prepare to be left breathless.”—Sophie Wan, author of Women of Good Fortune

What does it cost to pursue your wildest dreams?

Evelyn and Sophie, sisters and best friends, were known as one of the climbing world’s strongest teams—but that was before Evelyn had an affair with Sophie’s husband. Now they can’t even be in the same room together. That is, until they’re both offered a mountaineer’s dream: a chance to summit the eight-thousand-meter peak Yama Parvat.

Sophie has been aimless since Evelyn’s betrayal. She hasn’t summited a Himalayan mountain in nearly two years, all the joy drained from the sport for her, and this trek offers a chance to reestablish herself as a top climber before her sponsors withdraw their funding.

Evelyn has been happy with Miles since he left Sophie, but guilt continues to shadow her, clouding her judgment and the ability to move forward. Now she’s willing to gamble everything for the chance to be part of the first team to summit this as-yet unclimbed mountain and prove herself a capable leader.

Stranded during a devastating storm on top of the world, Evelyn and Sophie are forced to climb together. Whether or not they make it off the mountain alive hinges on their trust in one another—something lost years ago—as they face down the question of how much they’re willing to sacrifice to get it all back.
