Her name is Dr. Harleen Quinzel—better known to her friends and enemies as Harley Quinn. Her very-very-ex-boyfriend the Joker may be the Clown Prince of Crime, but Harley’s the Queen of Coney Island! So when the zombie apocalypse threatens her li’l seaside stretch of paradise, who else would ya call to give the undead a blow to the head?

In Gotham City, heinous acts of violence occur daily. Harley Quinn, forensic psychiatrist and profiler, consults with the Gotham City Police Department on its worst cases. But one unsolved murder still haunts her-the night Harley discovered her roommate’s body marked with the signature of a notorious serial killer known as The Joker. Five years later, the case remains unsolved, as a new series of horrific killings begins. When the murders escalate and the meticulously constructed crime scenes become more elaborate, Harley’s obsession with finding the depraved psychopath responsible leads her down a dangerous path. The past and the present finally collide, and Harley must decide how far she is willing to go-and how many lines she is willing to cross-to solve these cases once and for all.
