It’s been a year since Billie Flanagan—a beautiful, charismatic Berkeley mom with an enviable life—went on a solo hike in Desolation Wilderness and vanished from the trail. No body—only a hiking boot—has ever been found. Billie’s husband and teenage daughter cope with her death the best they can: Jonathan drinks, Olive grows remote.
But then Olive starts having waking dreams—or are they hallucinations?—that her mother is still alive. Jonathan worries about Olive’s emotional stability, until he starts unearthing secrets from Billie’s past that bring into question everything he thought he knew about his wife. Together, Olive and Jonathan embark on a quest for the truth—about Billie, their family, and the stories we tell ourselves about the people we love.
