But beneath the gilded surface, this utopia is rotting with prejudice and oppression – and Kamala must find an unlikely ally in schoolteacher Kitty Pryde to help her learn to live in this brave new world. But if Kamala is here…so is Legion! What dangerous power will he unleash – and can Kamala recruit allies in time to stand against him? Or will she – and all of mutantkind – be newly decimated?
