Regarding my previous note about the "Unofficial Harry Potter Cookbook" - I had written that the recipies were all Kosher. This is wrong. The author herself keeps Kosher, and most of the recipes there are indeed Kosher, but she writes in her acknowledgments that she had the help of a non-Jewish (and non-Kosher-keeping) chef in preparing a few recipes that are not Kosher.
It still looks to me like this cookbook will be a lot of fun for families with Harry Potter fans, but Kosher-keeping readers should know that (as with all non-Kosher cookbooks) there will be recipes to skip or adapt.
While I'm writing, I'd like to continue to recommend Time Out - Sports Stories as a Game Plan for Spiritual Success by my friend, neighbor, and name-sharer Rabbi Dov Lipman. Sports fans or their parents will find the book a fun way to relate to Judaism and spirituality.
