The Collector isn't exactly a comfortable novel to read. I remember we read an extract during my English Literature A Level and everybody hated it, because the narrator is a creep. Having read The French Lieutenant's Woman, though, I wanted to try some more of Fowles' writing. It's very readable and interesting, despite the disconcerting themes.
I don't really like the fact that you have to read the whole plot through both points of view, but it makes sense. They're both unlikeable, actually. Frederick because of what he does, and Miranda because of the way she writes. 'La-di-da' is a good way to put it. Not that that should make anyone think 'she deserved it', but it does make her less of a martyr figure, and more real.
