With new revelations about their home planet--and the man who destroyed it--Supergirl builds a star cruiser using whatever tech she can scrounge, and after intel from Green Lantern, she blasts off into the cosmos with Rogol Zaar's deadly axe to solve the mystery--along with a traveling companion you won't believe!"-- Provided by publisher.
