People often ask for book recommendations on italki, and I never know what to say because I don't usually notice whether books are in easy or difficult English. 

I'm starting to read a novel by Kurt Vonnegut--"Galápagos"--and it occurred to me that the actual English in his books seems to be structured in a plain and simple way. However, of course, he uses a lot of ironic humor and cultural references.

One example of his writing that can be found online at no cost is a short story, entitled "2 B R 0 2 B,"
