When a teenage girl is found dead on a quiet suburban street, Detective Meredith Somerset is haunted by flashbacks to the day her little sister vanished--the day Meredith should have been watching her. But with a murder to solve, she doesn't have time for painful memories to cloud her judgement. The victim is shoeless, the only clue to her identity a small silver medallion hidden in her grass-stained sock. Did she run from her killer across the smooth lawns of Willow Lane? And if so, how did no one in the surrounding houses see or hear a thing? Meredith needs answers, or she'll never shake the image of her sister's face begging her for help. But Willow Lane has more than one mystery behind its doors-and to find the killer, Meredith must venture into a community that's determined to keep its secrets hidden at any cost...
