A book that you’ve read more than 3 times.
Honestly – I have never read any book more than 3 times. In fact, I can only think of one book that I have read twice: the first Harry Potter book. No wait, I have to take that back; I re-read a Harlan Coben book once by accident, I realized about 100 pages into it that I had read it before, but by then I had to know what happened since I could not remember. But generally I am not a re-reader. I just don’t like to do it. I know some people re-read books all the time, I just can’t seem to bring myself to doing it. There are too many books on my TBR … between the ones that I own and the ones that are on my virtual wishlist/reminder list, I don’t have the time to re-read.
