I tend to only buy books that I want to read again at some point, but there just seem to be those titles or authors that I will read constantly. One author is Isaac Asimov. Growing up, I loved reading all of his fiction simply because it was well written and well thought out. Now I like to read it so I can find out what's coming next in the world. I read all of his science fiction at least once a year; often more.

Others that I reach for more than most are John Grisham, Anne Rice, and now JK Rowling (but only the later Harry Potter- the early ones are tripe).

The only non-fiction book that I regularly go for is my Federalist Papers. The others get soaked in on the first sitting and I'm good

So what do you reach for more often than others?
