Scientist Grant McKay has done the impossible: he has punched through the barriers of reality in a desperate bid to unravel the mysteries hidden within the prime universe at the center of the Eververse. But what lies beyond the veil is not epiphany, but chaos. Now Grant and his family are lost, living ghosts shipwrecked on an infinite ocean of alien worlds, barreling through the long-forgotten, ancient, and unimaginable dark realms. The only way is forward, through the delirium of a million universes, with no way home.
