Arden Maynor was just a child when she was swept away while sleepwalking during a terrifying rainstorm and went missing for days. Against all odds, she was found, alive, clinging to a storm drain. The girl from Widow Hills was a living miracle. Arden’s mother wrote a book, and fame followed. As soon as she was old enough, Arden changed her name and disappeared from the public eye. Now a young woman living hundreds of miles away, she goes by Olivia. But with the 20th anniversary of her rescue approaching, the media will inevitably renew its interest in Arden. Soon Olivia feels like she’s being watched and begins sleepwalking again, like she did long ago, even waking outside her home. Until late one night she jolts awake in her yard. At her feet is the corpse of a man she knows --- from her previous life, as Arden Maynor.
