Will Stanton must face a powerful agent of the Dark in this Newbery Medal–winning fourth installment of the epic fantasy series.

There is a Welsh legend about a harp of gold, hidden away within a certain hill. As the legend goes, it will be found by a boy and a white dog with silver eyes—a dog that can see the wind.

Will Stanton knows nothing of this when he comes to Wales to recover from a severe illness. But when he meets the strange boy Bran and his white dog, a startling rush of memory wakes within him. For Will is the last-born of the Old Ones, immortals dedicated to saving the world from the forces of evil, the Dark.

To prepare for the last battle between the Dark and the Light, the six who slumber in the Welsh hills must be woken. And it is Will’s task to rouse them with the golden harp. But first, with help from Bran, Will must face his most terrifying opponent yet: the Grey King.
