The action from last issue continues, with Harley Quinn in the custody of Amanda Waller and the apparent latest incarnation of The Suicide Squad. Harley has zero damns to give, however, so confident is she in an immediate rescue at Batman's hands. Meanwhile, Dr. Fate returns to the parallel Earth where he left a mostly-dead Black Canary, along with her newborn son, to give them a happy ending of sorts with an Oliver Queen who had lost his Dinah Lance at some point in the past. Hilarity ensues.
More about the story I cannot say. Suffice it to say that if you enjoyed the previous Injustice comic series, you will enjoy this one as well. It has the same great artwork and a story that will continually surprise you, one way or another.
