A book that I've read more than three times is The Count of Monte Cristo. This is actually my favorite book of all time AND the book that I've re-read most. I've read it so many times that I've actually gone through three copies. I have no idea what the actual read count is for it because growing up, I took this to the beach with me every summer. I can think of no better place for it. The sounds of gulls and crashing waves always help me to get swept away in this story.
If you haven't read this book yet, you need to. AND THE ABRIDGED VERSION DOESN'T COUNT.
