Query: This is one to keep

I usually buy CD books for my daily commute. Most of them I "read" and then I sell them. Angela's Ashes, however, will stay with me. The story is sad, because it talks about a difficult life, but it will also make you laugh. Overall, it's just a beautiful story. And you can't beat the pleasure of having the author reading for you. You simply know that he's giving each word the exact meaning it had for him when he wrote this book.
