Guy Kay's first contemporary fantasy is a tour de force-and his bestselling novel ever. Fifteen-year-old Ned Marriner accompanies his photographer father to Provence,where he is shooting images for a glossy coffee-table book. As Ned strolls along roads walked by Celtic tribes and Roman legions, he discovers a very old story playing itself out in this modern world of iPods and cell phones. On one holy, haunted night of the ancient year, when the borders between the living and the dead are down and fires are lit upon the hills, Ned, his family, and friends are shockingly drawn into this tale, as dangerous,mythic figures from conflicts of long ago erupt into the present, claiming and changing lives.
