First off, I loved Weirdstone a lot. Moon, not as much, but still, it's part of the story, so it must be read, right (the ending left me with very mixed feelings)? Boneland, well, it's hard to say. First off, it's a masterpiece. I love the writing, hate the story, feel mixed about the ending. Or do I love the story? Love and hate get so mixed up sometimes. All I can say is: it's an emotional roller-coaster. Anyone who can read Garner and not become emotionally involved is dead inside.
The book thrills me, entertains me, and depresses me all at the same time. I have the same problem I have will all his books: I hate for the story to end. And yet, as a True Story, it never ends, it just transfers ownership and I feel unworthy to continue it.
Read it or not at your own peril. Either way, you'll never be the same again...
