Horizon (Elemental Enmity Book IV)
Evil has many faces—unfortunately, Rayla Tate has seen them all, or so she thinks. Since she learned she was an Elemental, she has been hunted for her power. But Rayla hasn’t met her greatest foe; she hasn’t seen true evil…yet.
Rayla must unite with unlikely allies to destroy the evil plaguing Faeresia. For if she refuses, she will succumb to a compulsion she never could have anticipated.
