Now it's up to Harley to travel through both time and space to fix all the continuity errors she created. Luckily, she'll have a little help, 'cuz riding shotgun is none other than special guest star Jonni DC, Continuity Cop! Good thing, too, because if Harley fails, it means her own mom will be lost forever. Gulp! That doesn't sound very funny! This new era for the DCU's craziest anti-hero continues here in Harley Quinn Vol. 2. Collects issues #50-56.
