Do you like to read books a second (or third) time?

[mvccd1000]

I generally don't, but I'm re-reading part of a series this week, and in the May 27, 2012 weekly thread I noticed others who are reading books for the second (or more) time. That brought up the question:

What makes you enjoy a book for the second time around?

In my current case, I read 3 books with a new character by an author who had a previous character series I didn't know about. There were incidental mentions of the original character in the new series, so I went back and read those. Once I finished the 4 original books, I decided to reread the 3 that came later, now that I knew the locations and other supporting characters better. I'm enjoying them quite a bit the second time around. (The two series are the Lou Mason and Jack Davis series by Joel Goldman.)

Others I've read and enjoyed more than once are "Point of Impact" by Stephen Hunter (I've bought it, read it, and given it away three times - each time the person I've loaned it to has enjoyed it so much they just had to pass it on to someone else instead of returning it), and many of the early Travis McGee books by John D. MacDonald.
