A Change of Heart (Hestaesia #4) by KL Thorne:
 
Oriel, the scoundrel prince, is living in his brother’s shadow and hiding a shameful secret. Orphaned as a babe, Indi is taken in by kindly demoness Magna and raised as a humble farm girl, despite being faerie. Indi and Oriel meet and it’s love at first sight. For years, their lives are punctuated by Oriel’s infrequent visits - spending a few short weeks in paradise before he has to return to the demon city of Banesteppe. Their love seems infallible, marred only by Indi’s insistence to experience city life and the dark shadow of Oriel’s insecurities. Upon discovering her relationship with Oriel is not as perfect as she once thought, Indi accepts the help of witch and coven harbinger Tabitha. Under Tabitha’s bold influence, Indi starts a journey to decide who she really is and discovers there is life outside of love. Oriel undertakes a transformation of his own - learning to live with his heritage and what true love really means. Will the cracks that have begun to appear in their relationship shatter them beyond repair, or will their love for one another be enough to hold them together?
