Ten years ago, when Tessa was eleven years old, she was sleeping at a friend's house when they saw someone run through the yard. When their babysitter's body is found the next day, the police are investigating, and take the girls' statements--statements that point to a particular person, statements that get that man sent to Death Row. Tessa moved away. Callie stayed in town. Seven years have passed, in which time they've barely spoken. Now Tessa is back in town because her own imprisoned father is ill, and the memories of that summer night begin to unravel. Maybe what they saw wasn't who they thought. Maybe it was anything but. Maybe these old secrets need to be examined closely--or maybe left in the dark forever. 
 An engrossing story that pulls together several disparate threads by the end, though it did feel like we had too many mysteries happening at once for a while. Eventually they all come together in a reasonably convincing, teen-thriller-y way. 
 Would pass to high schoolers, maybe 8th graders. Some drinking, mentions of off-page sex and prostitution.
