When Annalee Ahlberg goes missing, her children fear the worst. Annalee is a sleepwalker whose affliction manifests in ways both bizarre and devastating. When the police discover a small swatch of fabric, a nightshirt, ripped and hanging from a tree branch, it seems certain Annalee is dead, but Detective Gavin Rikert continues to call and stop by the Ahlbergs' Victorian home. As daughter Lianna peels back the layers of mystery surrounding Annalee's disappearance, she finds herself drawn to Gavin, but she must ask herself: Why does the detective know so much about her mother? Why did Annalee leave her bed only when her father was away? And if she really died while sleepwalking, where was the body?
