One of the reviews on the book cover said it was "profound without being pretentious". I agree wholeheartedly. The characters felt real and honest. Funny and tragic. Wonderful and imperfect. Real people. People we know or are ourselves.
Here is a link to a New York Times review of the book.
I liked that this book was an easy read (I read it in a matter of a few hours), but at the end of it I didn't feel like I had just lost brain cells or shamed my reading ability.
