Harley Quinn (2000-) #23
Harley's missing in action following her fatally bizarre adventure "down under." Now, we find out what it's like to live in a "World Without Harley." So whom do we focus on instead? Why, Martian Manhunter, naturally! Seems J'onn J'onzz has picked up a new client in his guise as a private detective. But not everything is as it seems. So what's all this got to do with our Miss Quinzel? You won't believe the answer!
