Fourth in Susan Cooper's wonderful "The Dark is Rising" series, dealing with the ancient magic of Britain. Newberry Award Winner. Recommended!
There is a legend in North Wales about a harp of gold, hidden within a certain hill, that will be founs by a boy and a white dog with silver eyes-a dog that can see the wind. Will Stanton knew nothing of this when he came to Wales to recuperate from a severe illness. But when he met a strange boy named Bran and Bran's white dog Cafall, he began to remember. For Will was no ordinary boy, but the last born of the Old Ones, servants of the Light, immortals dedicated to saving the world from domination by the force of evil, the Dark.
A boy recuperating from a serious illness comes to Wales only to find that he's destined to fulfill an ancient Welsh legend.
I thought the Dark is Rising series was awesome. I liked it better then my 12 yo son did, but he liked it too.
Based off of a Welsh ledgend, this novel shows one more battle in the war of Good versus Evil. A boy must wake six warriors with a golden harp to fight in the last battle. The novel won the Newbery Honor and is recommended for ages 10 and up.
