For the grownups, The Vanishing of Katharina Linden by Helen Grant (Delacorte, 2010), reviewed in the Washington Post (8/23/10).  There's a lot to recommend this novel to adult readers of children's books, especially ones that have something to do with the Grimms (and there are an awful lot of them, readers and Grimm books alike):  the heroine, 10-year-old-Pia (and her only friend, StinkStefan), the setting, a small town in Germany; and the local folklore and traditions that inform the whole story.  PW describes it as a "charming horror novel" (4/12/2010).  I try to stay away from horror novels of any sort, but just look at that gorgeous yellow cover.
