This is a wonderful fantasy series. Simon, Jane and Barney are enlisted by their mysterious great-uncle to help fight the forces of evil, the Dark. Will Stanton, who appears to be an ordinary child, but is the last-born of the immortal Old Ones and therefore, not really an ordinary child at all, is also joining forces with them. They fight fear and death in the darkly brooding Welsh hills, in a quest through time and space that touches the most ancient myths of the British Isles.
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.
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.
