Mary Claire O'Brien has hidden for as long as she can remember. During the week, with her father away in the city, Mary Claire feels like every other child - but on Fridays, everything changes. On Friday mornings, she rises onto her tiptoes and wraps her nightgown tightly around her legs to silence the swooshing sound she loves. She slowly becomes invisible. Hiding is how she remains safe; it's how she protects her mother.

At ten years old, Mary Claire begs God to take her father away, but someone else has plans for him, and those plans will change everything.

Years later, Claire Stanton struggles with the secrets of her past, secrets she didn't know existed, secrets her mother holds tightly, right to the very end. After Claire's daughter becomes sullen and angry, she fears history may be repeating itself. With this new information taunting her, she takes matters into her own hands and vows to make the abuser pay, no matter who she destroys in the process.

Life is complicated. Secrets are destructive. But the truth is explosive.
