Every year, on her birthday, Laura gets a letter from a stranger. That stranger claims to know the whereabouts of her missing friend Bobby, but there's a catch: he'll only tell her what he knows in exchange for something... personal. So begins Laura's sordid relationship with her new penpal, built on a foundation of quid pro quo. Her quest for closure will push her to bizarre acts of humiliation and harm, yet no matter how hard she tries, she cannot escape her correspondent's demands. The letters keep coming, and as time passes, they have a profound effect on Laura. From the author of Cruel Works of Nature comes a dark and twisted tale about obsession, guilt, and how far a person will go to put her ghosts to bed.
