Apples Never Fall

Liane Moriarty builds her domestic mystery around that suspicion, then rewinds to a stranger named Savannah who turned up bleeding on the Delaneys' doorstep months earlier and never quite left. As in her bestselling Big Little Lies, Moriarty is less interested in forensics than in the fault lines of family - the resentments, secrets and self-deceptions that a crisis brings to the surface.

She keeps the whodunit ticking while dissecting a long marriage and the adult children still bruised by it, all laced with her trademark wit. The result is a shrewd, absorbing entertainment that uses the machinery of suspense to say something true about how little we know the people closest to us.
