My running expectation for the past few years has been that DC never announces any new books at conventions, so naturally... I wasn't expecting much from this year... Well, shame on me!
Coming sometime later this year, Harley Quinn will once again star in her own book from co-writers (and husband and wife) Jimmy Palmiotti and Amanda Connner. The artist has yet to be named, and there's no solid release date announced (I'd expect November), but hey! DC actually announced a new book!
Head over to CBR to read an interview with the writers, and expect me to cover this whenever it is released.
