I've just finished listening to Virginia Woolf's Orlando and I'm now unsure as to how I got to be 23 without it. It's a stunning book, much richer than anything I had expected. At once fantastic and somehow believable, and a fascinating commentary on the many facets (over 2,000?) of human nature and the strangeness of trying to commit and identity to the page.
If you have not read it, do so right away. I think this book will haunt me for a long time.
Also, I found out that I share a birthday with Virginia Woolf, and that has to make me pretty awesome, right?
