The Stars Are Dying [Special Edition] (Nytefall Trilogy, 1)

"In a world abandoned by the celestial guardians and left to suffer a tyrant king's reign, all Astraea knows is safety in seclusion. With fragmented memories of only five years of her life, she's determined to discover more about her past, even if that means fleeing the cruel arms that hold her safe from the wicked vampires rumored to roam the land."--publisher.
