"Wealth makes many friends,
But the poor is separated from his friend." -- Proverbs 19:4 (NKJV)
Think of Mrs. Dalloway as being the anti-Ulysses (the James Joyce's masterpiece). The concepts for the novels are similar, but the styles are polar opposites. I recommend becoming familiar with both works in order to appreciate the different ways that character studies can be developed during a day by relying extensively on thought life. Both are brilliant, but in much different ways.
Mrs. Dalloway is English, delicate, fussy, ornate, and feminine. Ulysses is Irish, crude, unrestrained, common, and masculine.
What stands out the most about Mrs. Dalloway are the many original descriptive sentences and phrases that look as though they went through 200 rewritings to be so polished and complete. Their expressions overwhelm the story at time because the reader is left gasping at a stunning turn of phrase or an idea. In writing, you can sit and admire and forget to read on.
A blessing of listening to the excellent reading by Virginia Leishman is that the brilliant writing is better integrated into the story by forcing you to keep going. I enjoyed the experience. I don't want to discourage you from reading the book first, but I believe you will appreciate the overall craft more if you listen before reading. It's the same advice I provide for William Faulkner's books. There's a beauty in the oral expression that is otherwise lost.
I found the story to feel a little dated. I also found myself not being terribly engaged by Mrs. Dalloway or her husband. That's a pretty big problem to have when listening to or reading a novel. Someone today who wrote historical fiction about this period would do it differently.
Naturally, if I were only rating the marvelous ornate writing, this would be five stars. Most writers can only sit back in awe of such writing. On my best day, I wouldn't be worthy of holding a candle for Virginia Woolf.
