YA. An eleven-year-old boy searches for six magical signs in order to save the world from the threatening evil of the Dark.

The Dark Is Rising

'When the Dark comes rising, six shall turn it back; three from the circle, three from the track; wood, bronze, iron, water, fire, stone; five will return and one go alone.' Susan Cooper's brilliant and absorbing fantasy sequence - the fourth volume of which, The Grey King, won the Newbery Medal - is here published in a single volume.

The Dark is Rising Sequence

This night will be bad and tomorrow will be beyond imagining. It's Midwinter's Eve, the day before Will's eleventh birthday. But there is an atmosphere of fear in the familiar countryside around him. This will be a birthday like no other. Will discovers that he has the power of the Old Ones, and that he must embark on a quest to vanquish the terrifyingly evil magic of the Dark.

Simon, Jane, and Barney, enlisted by their mysterious great-uncle, arrive in a small coastal town to recover a priceless golden grail stolen by the forces of evil -- Dark. They are not at first aware of the strange powers of another boy brought to help, Will Stanton -- nor of the sinister significance of the Greenwitch, an image of leaves and branches that for centuries has been cast into the sea for good luck in fishing and harvest. Their search for the grail sets into motion a series of distubing, sometimes dangerous events that, at their climax, bring forth a gift that, for a time at least, will keep the Dark from rising.
