In a world the gods have abandoned, Elara is the final priestess to a forgotten deity: the Heartless God, who legend says tore out his own heart after a bitter betrayal. When a desperate prayer in a ruined temple accidentally awakens his dormant consciousness, she finds not a benevolent figure, but a cynical, shadowy being of immense power who scorns her very faith. To restore him, she embarks on a quest to find his lost heart. But the truth is far more dangerous than the legends. His heart is not lost—it's hidden in the one place no one would ever think to look, and its discovery will ignite a war between mortals and a cosmic horror from beyond the stars.
