Elizabeth Lerner was kidnapped when she was fifteen years old. She spent the summer with her abductor, traveling with him and waiting for him to kill her, as she knew he'd done to other girls. Now she's Eliza Benedict, married with children of her own, and her abductor, on death row and months away from his death, has contacted her. She wants nothing to do with him, but he's sending veiled threats to reveal her identity to the press, and worse, to her children, who know nothing about her past.
So, this was women's fiction disguised as a mystery. There's a slow reveal to the events of 1985, with the chapters alternating between the present and the past. But there's not really a mystery at all. There are questions, yes--why didn't Walter kill Elizabeth as he had the other women, why had he taken her captive to begin with, what is it that he wants from her, after all these years? But it was more of a character study than anything else, and Elizabeth is certainly an interesting character--and of course, serial killers are always fascinating. It definitely held my interest, but in a Jodi Picoult way, not in a Harlan Coben way.
