Just the one thing his foe values most: Zola's son! Steve has saved the boy's life, but can he keep him alive against the savage barbarians of Phrox -- with the fate of a world hinging on his victory? And when Zola's terrible experiments on the indigenous creatures give birth to a terrible new foe, the Odd War of Dimension Z begins!
