A word of warning, however- since these ARE adult books, there will be adult content. Sex (married and unmarried), GLBTQ content, battles, fighting, etc., on an extent that may not be in teen science fiction/fantasy books. You know your reader, so recommend appropriately.
I'm not sure who was more upset in our house when Sci Fi (SyFy, my bad) cancelled The Dresden Files, That Guy or myself. I love the contemporary with magic world that Jim Butcher creates, and loved the portrayal that was going on TV. For teens that see magic in the every day, and want their magic combined with mystery, this is one of the best series around.
