Boneland - by Alan Garner

I went straight on to read this book and read it quickly, as it was my next book club book and I had very little time. Here’s the blurb:

‘A woman was reading a book to a child on her knee.
‘“So the little boy went into the wood, and he met a witch. And the witch said, ‘You come home with me and I’ll give you a good dinner.’ Now you wouldn’t go home with a witch, would you?”
‘Colin stood. “Young man. Do not go into the witch’s house. Do not. And whatever you do, do not go upstairs. You must not go upstairs. Do not go! You are not to go!”’
Professor Colin Whisterfield spends his days at Jodrell Bank, using the radio telescope to look for his lost sister in the Pleiades. At night, he is on Alderley Edge, watching.
At the same time, and in another time, the Watcher cuts the rock and blows bulls on the stone with his blood, and dances, to keep the sky above the earth and the stars flying.
Colin can’t remember; and he remembers too much. Before the age of thirteen is a blank. After that he recalls everything: where he was, what he was doing, in every minute of every hour of every day. Everything he has read and seen.
And then, finally, a new force enters his life, a therapist who might be able to unlock what happened to him when he was twelve, what happened to his sister.
But Colin will have to remember quickly, to find his sister. And the Watcher will have to find the Woman. Otherwise the skies will fall, and there will be only winter, wanderers and moon…

Overall, although I found the book interesting, I really did not understand all the layers of the story. I believe that some ambiguity is intentional. I am slight curious to read the first two books in the trilogy [but I have been warned that they might not elucidate matters much].
