The Raven Boys by Maggie Stiefvater is a YA urban fantasy that follows Blue Sargent, the non-psychic daughter of a family of clairvoyants, who has been warned her entire life that she will cause her true love to die. On St. Mark's Eve, she sees the spirit of a living boy for the first time — a wealthy student from the local Aglionby Academy named Richard "Gansey" Gansey III. Soon pulled into Gansey's obsessive search for the ley lines and the resting place of a long-lost Welsh king, Blue joins forces with his circle of friends as they uncover ancient magic and dangerous secrets tied to their small town.
