I strongly advise against Virginia Woolf's "Mrs. Dalloway," unless you have the mind to find your way out of intense mazes. I attempted to read this book and got 50 or so pages in before realizing that I had absolutely no idea as to what was going on. It's primarily stream-of-consciousness, so, again, I advise against reading it without the aid of hallucinogenic drugs.
I strongly advise that everyone at least attempt her. She is not my favorite but is sosososososo important to the Modern movement. And many of her techniques and styles are being used today.
FACT: She totally stole the idea for Mrs. Dalloway from James Joyce's Ulysses.
I really enjoyed Mrs. Dalloway. You have to get into a different mindset when you read, but I think it's pretty amazing. I dunno. I preferred it a lot over contemporaneous stream of consciousness reads.
As far as I'm concerned, Virginia Woolf > James Joyce.
