When I was growing up in Chicago, my family and I used to go to a local chain, Hackney's, for burgers and their French fried onion loaf. I probably haven't been to one in 25 years, and yet, I once saw Donald Trump from behind in an office building and the first thing that flashed in my mind was his hair looked like that onion loaf.

'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.
