Twelve-hundred years ago, the Bloodmoon shattered. Now, a single, wrathful shard has fallen into Skeltryal. The Reckoning has begun. On a night that should have been like any other, a wrathful shard comes crashing into the Astern Sea, igniting a clash between those devoted to the Blood gods and the worshipers of the Celestial realms. As the wrath of the gods stir once more, Skeltryal is threatened with a war that could reshape the world into a living Abyss. Mysteries are unraveled and tensions rise between the four elemental kingdoms. Six must find their place. The astronomer, who will unravel the Blood gods' dark ambitions; the assassin, bound to Insanity; the atheist, conflicted by belief when fables become reality; the Bloodkissed, discovering forbidden truths in the lands of the lost; the Scholar, who defies his sanctum's laws to stop a looming war; and the Hollow, who begins a descent into darkness from which he may never return. As fate draws their paths together, each must choose where they stand in the coming storm-beneath the Bloodmoon's wrath or against it.
