*Ana Reyes, New York Times bestselling author of The House in the Pines

Twenty years ago, the members of a reclusive commune outside Philadelphia vanished without a trace. The mystery of their disappearance has never been solved. No sightings of the members were ever verified, and no bodies ever found. But the group did leave one thing behind: a twelve-year-old girl wandering alone on the side of the road in search of her lost family.

In the years since that morning, Lee Burton has tried to put the pain of her past behind her. She has built a new identity for herself, with a doting husband and seven-month-old daughter, Lucy. No one in her life now knows about her connection to "the cult that went missing," not even her husband. But new motherhood is proving a bigger challenge than she anticipated. She doesn't want to let Lucy out of her sight even for a moment. She can't return to work. She's not sleeping, and she's starting to have paranoid thoughts of Lucy being harmed.

Then a stranger shows up on her doorstep, offering to finally answer all of Lee's questions about her past--if she could only trust that the woman is who she says she is. As she digs deeper into the woman's history, the safe, stable life that Lee has constructed for herself threatens to shatter. In The Ascent, Allison Buccola has crafted a nerve-rattling thriller about motherhood, identity, and the truths we think we know about our families.
