Emma in the Night

At the start of this searing psychological thriller from Walker (All Is Not Forgotten), Cass Tanner returns home alone—three years after she vanished at age 15 from a beach on Long Island Sound, along with her then 17-year-old sister, Emma. Cass tells a detailed story about being held captive on an island in Maine, but she’s oddly short on specifics that would help locate the site. FBI forensic psychologist Abigail Winter, one of the original investigators, gets back on the case. Abby believes that the girls’ disappearance is related to emotional turmoil within the family. Cass and Emma fought bitterly, egged on by their divorced mother, Judy Martin, who thrived as a minor celebrity after her daughters went missing. Cass believes that the only one who really “sees” the family’s problems is Abby, whose own mother was much like Judy. Walker’s portrayal of the ways in which a narcissistic, self-involved mother can affect her children deepens the plot as it builds to a shocking finale. 125,000-copy first printing. Author tour.
