It's about a group of 5 women who live on the same street and start up a book club. It kind of chronicles all of the stuff they go through in raising their kids, life with their husbands and various other issues... it's a huge book. I read it super quickly because the writing was awesome, and the characters were great. I really wished they were real, and I'm sad to be done with the book! I think I'll read it again someday... there are a lot of sections that might read really differently after you've had and raised kids. So, note to self: In 30 years, read this book.
I highly recommend this book - it's a quick and engaging read and well worth it.
