I am often asked the question: 'What is your favorite type of food?' Although I always answer Japanese, the real response should be and is pierogi, the delectable Polish dumplings that my mother, Big Martha, made so well in many incarnations: potato, sweet cabbage, blueberry, peach, plum, and apricot.

'Star Wars,' 'Doctor Who,' 'Forgotten Realms,' even 'Firefly' and 'The X-Files' have shared world novels and other media. I can't help but notice these settings have large shelf space in bookstores, so their publishers and authors are getting something right.
