It’s been a year since Billie Flanagan—a beautiful, charismatic Berkeley mom with an enviable life—went on a solo hike and vanished from the trail. No body, only a hiking boot, was ever found. Her husband and teenage daughter have been coping with Billie’s death the best they can: Jonathan by drinking, Olive by growing remote.  

But then Olive starts having waking dreams—or are they hallucinations?—that her mother is still alive. Jonathan is worried about Olive's emotional stability, until he starts unearthing secrets from Billie’s past that bring into question everything he ever knew about his wife. Is it possible that Olive is right—that Billie isn’t dead after all? 

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.
