Crowns of Nyaxia - The Nightborn Duet Tome 1 - Grand Format

The adopted human daughter of the Nightborn vampire king, Oraya carved her place in a world designed to kill her. Her only chance to become something more than prey is to enter the Kejari : a legendary tournament held by the goddess of death herself. But winning won't be easy against the most vicious warriors from all three vampire Houses. To survive, Oraya is forced to make an alliance with a mysterious rival.
Everything about Raihn is dangerous. He is a ruthless vampire, an efficient killer, an enemy to her father's crown... and her greatest competition. Yet what terrifies Oraya most of all is that she finds herself strangely drawn to him. But there's no room for compassion in the Kejari - and nothing more deadly than love...
