Argumento

From the nightmarish return of Krypton to the machinations of Cyborg-Superman, Kara is thrust from one battle to another until a fight with Lobo sends her over the edge...an edge filled with rage. Will the flame be pulled from her heart or consume her forever? And what is this deep-space school called the Crucible all about?
