I really struggled with it the first time JJ, I think because it's written in the first person so that's the identifier but you really don't want to identify with her, she's hideous, but then you don't want to identify with the main chracter as they're equally hideous and actually it's the sub characters you feel sorry for... i remember the first time I read, so many times I actually nearly threw it out the window because it made me so angry! But then that's why I think it's such a good book because to make me have a reaction like that it just has to be. I re-read it every six months or so and I can't say I 'enjoy' it exactly, but I do like it.
I also really like Will Self's Being Dead (I think it's called) and Irvine Welsh's Filth (very gross and need a strong stomach to read). Other good ones include Memoires of an Agnostic Dwarf, most of Jane Austen (but not Emma!), Frankenstein, Dracula and I'm sure there's more that I can't think of at the moment!
Did you ever get round to any Christopher Brookmyre (sp)? He writes an enjoyable yarn, good fun.
