Foal's Bread will be a controversial book, with readers either loving or hating it. It is subtle, but raises a lot of issues. The writing is clunky (I keep referring to it that way, because it doesn't flow well) because of the way the characters talk, and the fact that the narrator also takes up their style of speech and expression.
I'm not going to comment too much more, because I don't want to spoil the ending. But, I will say, that this last quarter was very powerful and tragic for many reasons. Look back over Part 1, Part 2, and Part 3, if you haven't already read them.
Please, if you pick up this book, persist.
