Cursekeeper

Thalia Morrow has spent her life guarding the Library of Curses. But when a mysterious demon known as the Lighteater ransacks the Library, stealing a deadly curse and kidnapping her brother, Thalia will do anything to find him.
Her search leads to Soren, a ruthless Fae Prince banished from his kingdom and cursed for his bloody past. Together, they strike a dangerous bargain: Soren will help rescue her brother if Thalia destroys his curse.
But as darkness consumes the realm and war looms, Thalia must decide whether she can trust the prince she’s falling for―or risk losing everything.
