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.
