Baal rules Seraphina. Atlantis is in his crosshairs. Thanks to Conrad Edison, Justin and gang can finally get back to Eden and raise an army to fight Baal. More importantly, Shelton can get a much-needed taco. But the Overworld lies in ruins after Victus's civil war tore it apart. Even worse, an anti-supernatural nom organization is systematically hunting down supers and taking over Obsidian Arch waystations. Justin and gang are running out of time to fight off the noms and restore order.
