Join Milo and Emma Banks, twin siblings from a small American town who dream of becoming something more, as they discover an electrifying family secret: they are not human at all, but demigods directly descended from a group of long-vanished deities who ruled over another world. That realm—called Astros, Land of the Gods—is about to become their new home.
But a darkness none of them could have imagined is settling over the land. Trapped in this unfamiliar, mythical world, Milo and Emma will have to band together with a ragtag group of orphans who each have their own parts to play in a global war that has already begun. Their only salvation is Theus Academy, a school of magic located across an ocean guarded by their enemies, where learning the secrets of long-vanished gods will be the only way to stop one of them—the most evil god of all—from rising to destroy all humans and demigods alike.
