The Harley Quinn in the nine-issue series won’t be the cartoon character audiences are familiar with; instead, she’s a forensic psychiatrist and profiler working the case in consultation with Gotham City authorities who’s edging ever closer to discovering the truth about the serial killer terrorizing the city.

This isn’t the first DC comic book for Garcia, a New York Times best-selling novelist for her work on the Beautiful Creatures series; she’s also working on the company’s YA Teen Titans series of graphic novels with artist Gabriel Picolo, which launches next month with Teen Titans: Raven. Joker/Harley will be illustrated by Mike Mayhew and Mico Suayan.

“When Kami came to us with the idea of profiling one of the most mysterious and dangerous characters in the DC Universe, it felt so new and original,” added DC publisher Dan DiDio. “Kami, Mico and Mike are taking great care to ensure that the mystery surrounding the Joker and Harley Quinn remains intact, while delivering a story that’s both compelling and haunting. This series is exactly the kind of unique, standalone story that’s perfect for DC Black Label, one we hope will engage both casual and new fans of these characters.”

The series is the latest title for DC Black Label, the imprint announced last year to allow creators the chance to use fan-favorite and iconic characters in stories that aren't required to tie into the monthly continuity of the mainstream DC titles. Other titles in the line include Batman: Damned and the upcoming Superman: Year One by Frank Miller and John Romita, Jr.

The first issue of the series, unveiled Sunday during DC’s panel at BookCon in New York City, is set to be released Oct. 2, with subsequent issues available on a monthly schedule.
