Well, after a long dry winter of no Amish in SF/F/H, I was checking out some of the places I've submitted to check on what's going on. I hit OSC's Intergalactic Medicine Show and there, in this issue, is Rumspringa by Jason Sanford. I don't know Jason (at least by name), but another writer including the Amish in his SF/F work. Cool! I just googled him and his stuff looks interesting.
As Tobias is all about the Caribbean (Jason has interview Tobias! Excellent), I'm about exurbia (back to the farm) and the Amish. It's what we know. The Amish aren't in every story I write, but they certainly make up some of the supporting cast in much of my Fantasy. Some in my writers group wonder why I don't put more of them in (or work them into other stories). Well, I'm not always about exurbia. Some of my characters are very urban.
But, cool. Amish are published in SF.
