I'd Know You Anywhere by Laura Lippman
Eliza Benedict, a 38-year-old married mother of two living in suburban Maryland, receives a letter from Walter Bowman, the man who kidnapped her the summer she was 15 and is now on death row. The narrative shifts between the present and that long ago summer, when Eliza involuntarily became a part of Walter's endless road trip, including the fateful night when he picked up another teenage girl, Holly Tackett. Soon after Walter killed Holly, Eliza was rescued and taken home. Eliza must now balance a need for closure with a desire to protect herself emotionally. Walter wants something specific from her, but she has no idea what, and she's not sure that she wants to know. All the relationships, from the sometimes contentious one between Eliza and her sister, Vonnie, to the significantly stranger one between Walter and Barbara LaFortuny, an advocate for prisoners, provide depth and breadth to this absorbing story.
