Twenty years ago, the Lovelorn Killer murdered seven women, before penning them gruesome love letters in the local papers. When amateur sleuth Grace Harper tries to prove that he's still living nearby, she winds up dead. Detective Annalisa Vega lost someone she loved to the killer, and in her debut outing, she will have to reopen the biggest murder case that Chicago homicide never solved. To figure out what Grace knew—and see a killer who is lying in wait—she will have to look back to her childhood, peering into dark corners she hadn't acknowledged before, and learn that she has still so much more to lose.
