Cooper, Susan, Greenwitch Bk 3

Simon, Jane and Barney, enlisted by their mysterious great uncle, arrive in a small coastal town to help recover a priceless golden grail stolen by the forces of evil, the 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 disturbing, sometimes dangerous events that, at their climax, bring forth a gift that, for a time at least, will keep the Dark from rising.

Jane's invitation to witness the making of the Greenwitch begins a series of sinister events in which she and her two brothers help the Old Ones recover the grail stolen by the Dark.
