I don't keep count of how many times I reread but these are some books over read more than once:

• The great Gatsby

• 11/22/63

• The secret Garden

• A Gentleman in Moscow

• Pride and Prejudice

• Memoirs of a Geisha

• American Gods

• Tommyknockers

Honestly, I can't really say for sure why I reread some books and not others, obviously the ones I reread are books that I enjoyed, but on the other hand there's a lot of books that I enjoy that I never reread. It's an interesting question that I can't necessarily answer.
