Over Sea, Under Stone (The Dark Is Rising Sequence)

"I DID NOT KNOW THAT YOU CHILDREN WOULD BE THE ONES TO FIND IT. OR WHAT DANGER YOU WOULD BE PUTTING YOURSELVES IN."

Throughout time, the forces of good and evil have battled continuously, maintaining the balance. Whenever evil forces grow too powerful, a champion of good is called to drive them back. Now, with evil's power rising and a champion yet to be found, three siblings find themselves at the center of a mystical war.

Jane, Simon, and Barney Drew have discovered an ancient text that reads of a legendary grail lost centuries ago. The grail is an object of great power, buried with a vital secret. As the Drews race against the forces of evil, they must piece together the text's clues to find the grail -- and keep its secret safe until a new champion rises.
