The boys are back! Picking up where the sensational Adventures of the Super Sons left off, the son of Batman and the son of Superman are back in the spotlight and ready to give evil a good spanking. A mysterious woman from beyond time has appeared to the DCU's favorite sons, and her arrival heralds certain doom (that's a hint, everyone) for things to come! It's a time-twisting adventure that casts our favorite super-spawn as the saviors of the Justice League-battling the likes of Vandal Savage, Felix Faust, and heavy grocery bags along the way! This volume collects Challenge of the Super Sons #1-7.
