Worlds' Finest (Renaissance), book 3: Control Issues
Paul Levitz et Collectif2014

To their foes, they're called Power Girl and Huntress. To their friends-and the best friends they have are each other-they're Karen Starr and Helena Wayne. But what they really are is women without a world.

Transported to an unfamiliar Earth by the minions of Apokolips, this dimension-hopping duo remains dogged by Desaad, Darkseid's most sadistic servant. Their fear fuels his madness-and is a crucial component of his next sinister plot. And with all they've lost, their fear is plentiful.

But it's a fear they must overcome. Desaad will stop at nothing until Huntress becomes the hunted...and until Power Girl is rendered powerless. Will they remain the World's Finest...or will they reach their final battle.
