The Trials of Shazam

Hercules is imprisoned. A mystical battle, which the police mistook for a gang turf-war, leaves him stuck in jail. For all his power, he cannot leave. After Freddie refused to break him out to win his power, Sabina stole a measure of that power. Now, having been given the other half of the strength of Hercules, Freddie must survive Sabina's onslaught. But where Freddie's fighting skill had come from the magic that granted him power, Sabina has been well trained in the arts of combat. If Freddie can't defeat her, then she will be the sole heir to the power of SHAZAM.
