Multiversity Harley Screws Up The DCU #4

Synopsis

How can Harley stop herself from screwing up the timeline if her future self has already screwed it all up? First she discovered she totally stopped Superman and the Flash from ever existing, and now she's finding out that she totally time-traveled right over Wonder Woman's and Aquaman's origins too! Harley has to stop Harley, or at least try to put the pieces of the DCU she's broken back together again. With a time machine and a tough, scary, alternate-universe Harley at her side, maybe--just maybe--she can make things right again.
