Twelve-year-old Hailey Newcomb slipped through the ice, going without a heartbeat for eight minutes. When she woke up in the hospital, everything seemed normal...except for one thing: she had memories that didn't belong to her. Hailey soon determined the memories belonged to Grace Mitchell, a local college student who recently disappeared without a trace. Through flashbacks and whispers, Grace lets Hailey know that she'd been murdered. And now it's up to Hailey, with guidance from Grace, to find the killer before he strikes again.
