Dr. Willa Watters is a prominent child psychologist at the height of her career. But when a viral video of a disastrous television interview puts her reputation on the line, Willa retreats to Broken Bayou, the town where she spent most of her childhood summers. There she visits her aunts' old house and discovers some of her unstable mother's belongings still languishing in the attic--dusty mementos harboring secrets of her harrowing past.

Willa's hopes for a respite are quickly crushed, not only by what she finds in that attic but also by what's been found in the bayou.

With waters dropping due to drought, mysterious barrels containing human remains have surfaced, alongside something else from Willa's past, something she never thought she'd see again. Divers, police, and media flood the area, including a news reporter gunning for Willa and Travis Arceneaux--a local deputy and old flame.

Willa's fate seems eerily tied to the murders. And with no one to trust, she must use her wits to stay above water and make it out alive.
