Empire of Blood #1 Life in the perilous Thorn district is a constant battle for Arvelle and her younger brothers. And the vampire standing on her doorstep is about to turn their world upside down. Faced with an unthinkable choice, Arvelle makes a magically binding vow to do the impossible: kill the emperor, an ancient vampire created by the god Umbros. But first, she must enter the Sundering—an arena where only the fastest, strongest, and deadliest survive long enough to be selected for the emperor’s elite guard.
