Ah yes, I remember that one. Pretty gruesome.and I'm reading 'The Wasp Factory' by Banks. Disturbing stuff.
I have just finished all the 'easy reading' stuff I had around, so I am currently chewing my way through the books that had accumulated at the bottom of my bookpile:
Re-reading Darwin's The Origin of Species (monumental, but a bit dry)
Jelinek's Die Kinder der Toten (dire)
Shakespeare's Sonnets
Dylan Thomas' Collected Poems
on an excellent choice. Even though the book is meant for young adults, some of the concepts and moral/ethical situations presented are clearly far more detailed than that and I think there's something for everyone to learn in there. If you enjoy it, there are other books in the same storyline by Card that you can take a look at and pick up. Highly recommended, all of them.
