Who Eugenie can trust is the hardest part. Fairy king Dorian has his own agenda for aiding her search. And Kiyo, her shape-shifter ex-boyfriend, has every reason to betray her along the way. To control the Crown's ever-consuming powers, Eugenie will have to confront an unimaginable temptation, one that will put her soul and the fate of two worlds in mortal peril.
