Musing Mondays - Re-reading a Book

Today’s MUSING MONDAYS post is about re-reading…

Have you ever finished a book, then turned around and immediately re-read it? Why? What book(s)? (question courtesy of MizB)

I have to say, I rarely re-read a book because I have too many books to catch up on than to re-read a book I have just read. Don't get me wrong, that does not mean I don't like the idea of re-reading a book, I do. It is just that I will not re-read it immediately. Most of the times, I will wait for a while (it can be months, or even years) before I will re-read a book. Other times, it is simply because I have forgotten about a book I had read for a long time and I want to re-read it to refresh my memory on it.

What about you? Do you re-read a book immediately, and why is it so?
