We Who Will Die (hardcover) Stacia Stark

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 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.

She quickly draws the ire of the Primus, the powerful figure charged with protecting the emperor. But the vampire under the armor is the last person Arvelle expects to encounter in the emperor’s court.
