A Court This Cruel and Lovely

In a world where humans lose most of their power to the gods shortly after birth in exchange for protection against the fae, those who retain their magic are branded corrupt and put to death. When a young woman's hidden, forbidden power is discovered, she must flee her village. To survive, she strikes a bargain with a mercenary who once left her for dead: she will help him and his companions enter the city, and in return he will teach her to control her strange, dark magic. But the mercenary carries secrets that could endanger everyone she loves and threaten the kingdom itself.
