Having just finished it, I completely loved Nightwood, being the type of reader that goes heavily for imagery and metaphor, and found it one of the most exciting, fascinating books I've ever read, like the warped love-child of Virginia Woolf and Charlotte Brontė. Challenging, yes, but I found it much more accessible than, say, Ulysses, which I never could get on with. I just let it wash over me. Vital, visual, unique; can only say that I found it breathtaking. I have read modernist writers before, so might be accustomed to oddities, but do not be scared off; it's writing that's alive and wild, and good grief, it's brilliant. I liked the way it takes the imagination into new and strange places, with such energy. This is what I read for.
