It's been a full year since the mystery that brought together antique shop owner and part-time amateur sleuth Sebastian Snow with homicide detective Calvin Winter. Patience, sanity, and their very lives have been put to the test, but love has persevered. Although Sebastian is now New York City's best-known busybody, he's finished with crime solving and wants nothing more than to plan a romantic budget wedding.
Then Snow's Antique Emporium receives a decapitated human head in the mail and the holidays are gory once again. Sebastian patently disregards the mystery of a lifetime because he is done with death and danger—but the killer escalates. Before Sebastian knows it, his closest friends and family are dragged into a series of horrific murders with antiquated clues hinting to the infamous Victorian American Bones Wars. The clock is ticking to recover a long-lost artifact linked to paleontologist Edward Drinker Cope and to capture a murderer.
But it's not Sebastian who may become the next target—it's Calvin.
