The Dark is Rising is a wonderful classic fantasy series, and 'Greenwitch' (Book 3) brings together the characters from Books 1 and 2, as the powers of the Light continue on their quest to overcome the Dark.
The Drew children, Simon, Jane and Barney, central to the story in 'Over Sea Under Stone' (Book 1) come back into the plot, returning to Trewissick with their Great Uncle Merry for a week of their Easter Holidays. They are on a mission to recover the celtic golden chalice they found in Book 1 and presented to a museum for safe-keeping. The chalice has been stolen and Great Uncle Merry (Gumerry) believes they can help to find it. In 'Greenwitch' their characters are better developed than in the first book, bringing out distinctive individual characteristics for each of the children.
Also on his way down to Trewissick for his holidays is Will Stanton, the Sign-Seeker and youngest of the Old Ones, guardians of the Light in Book 2. Will's Uncle Bill is taking him on his holidays with an old friend of his, Merriman Lyon... Merriman, or Merry has brought all of the children together for the first time as they each have unique skills to help with the recovering of the chalice and the fight against the powers of the Dark. Jane, in particular, as she is invited to watch the local women of the village construct the magical Greenwith as an offering to the sea, makes a wish which becomes important to the Old Ones in their struggles against the Dark....
Not as good as Book 2, but 'Greenwitch' is essential in bringing together the two plot lines established in Books 1 and 2, and is a key part of The Dark is Rising series. A great series for all ages.
