An unlikely group stumbles across ancient magic in Virginia: Blue, the daughter of the town psychic in Henrietta, Virginia, who has been told for as long as she can remember that if she ever kisses her true love, he will die. Gansey, who seeks the Welsh magic he believes saved his life. Adam, who searches for a way out of the circumstances he was born into. Ronan, who seeks to recover the magic of his childhood.
