From visionary writer Grant Morrison, the fourth volume features a high-stakes superhero epic where Earth's greatest heroes face escalating threats and realities that test their power, strategy, and trust. The Justice League continues its mission to protect the world, but the threats they face are growing more dangerous, more unpredictable, and more personal. As Batman, Superman, Wonder Woman, Aquaman, Green Lantern, the Flash, Martian Manhunter, and their allies confront threats that span worlds and dimensions, the League finds itself tested in unexpected ways. New allies join the team, old assumptions are challenged, and the bonds holding Earth's greatest heroes together are pushed to the brink. Led by writer Grant Morrison, with contributions from Mark Millar, Mark Waid, and Devin Grayson, this volume continues a landmark era of JLA, combining globe-spanning adventure, imaginative science fiction, and larger-than-life heroism. From interdimensional mysteries and cosmic conspiracies to battles that threaten the future of humanity itself, this volume showcases why JLA became one of the defining superhero team books of its generation.
