Forever Evil by Geoff Johns

A tyrannical team of alternate-universe supervillains conquers Earth after the planet’s greatest heroes are mysteriously defeated, forcing ordinary citizens and imprisoned rogues to resist under brutal occupation; with the Justice League absent, a calculating genius steps into the leadership vacuum, forging uneasy alliances with antiheroes and villains to fight back, uncover the invaders’ scheme, and wrestle with shifting loyalties and moral ambiguity in the struggle to reclaim the world.
