Soul (Chaos #1)
by Claire Farrell
Cara Kelly's life is going nowhere when she's lured to a faery festival, but afterward, things get too exciting. The faery she's fallen for now shares a body with a charming king who's only wish is to take back his crown. Helping him will help humans everywhere... and end the life of the faery she cares for. The stakes are high, and Cara's liable to lose everything to the faeries before the end.
