Night Blood Saga: Dominion of the Rift. The Blood of Endovelico

When the ancient balance between worlds begins to collapse, Endovelico faces the greatest threat existence has ever known. After the rise of the Void and the fragile peace between humans and vampires, a new danger emerges-something older than the Dark Realm itself. A force known only as the First Hunger, a primordial entity that existed before kingdoms, before bloodlines, before even death had rules.
As Europe fights to build peace between humans and vampires, powerful enemies in the United States seek to destroy that future by reopening forbidden paths between worlds. Ancient artifacts are uncovered, alliances are tested, and the mysterious Architect reveals a terrifying truth: vampires were never monsters-they were exiles from an older empire of eternal night. But the greatest revelation is far more personal.
Endovelico is not merely part of the war-he is the key to it. The lock between worlds. The final barrier standing between Earth and total annihilation. Forced to choose between unimaginable power and the people he loves, Endovelico must decide what kind of king he will be-one who rules through fear, or one who sacrifices everything for love.
