I have been reading The Mortal Instruments series. I have been enjoying it. It's easy, which always fun, but it does deal with good and evil a bit. The way the author, Cassandra Clare, deals with good and evil is interesting. She even makes room for the grayer shades. She asserts that only demons, at least in this "world," are the only really evil things. Anyway, I think I may read the books again just to see if they would stand the test of time before buying them.
