I tried to give you amazon links, but the poll did not like it. And yeah, I have 42 items out from the library, this is just the six that come due the soonest. (I try to read somewhat in order of when I get them out unless a book comes through that needs priority because it's popular.)
So help me out and give me advice on what to read next.
