I am on a re-read spree right now. Since the beginning of the month, I have only read one book (out of 7 so far this month) that was new to me. Other than that one, everything else has been a re-read. I have absolutely no problem with re-reading books. Especially if they are ones that I bought and have sitting in my house all the time. If I spent the money and read it once already, I am almost certain to read it again. Part of it is because I know that it's a story that I really like (or absolutely love). Part of it is that sometimes I want to read a story that is familiar and well-known, one that I have parts memorized or etched into my memory. And part of it is convenience. If it's on my shelf I don't have to worry about driving to the store and picking from countless titles to find something that may not be as good or one that I may not love as much. One of the series that I think is totally worth re-reading over and over again and the one that I am currently re-reading ...
