The Sisters Grimm, Problem Child by Michael Buckley. I am thoroughly enjoying these books. "We are Grimms and that's what we do." They are fairy-tale detectives, saving the world from fairy-tale creatures gone wild. The only thing that is driving me crazy about them is the lack of passage of time. All four books take place in a month or maybe two. It is annoying that all of these adventures are so crampacked into December. It is not enough to keep someone from reading the books, however. They really are fun.
