Continuing my Detroit/Michigan state of mind I just thought to look up Saladin Ahmed, I didn't really know him but when I lived in Michigan I'd seen him perform his poetry at an event or two and we had some friends in common. Apparently since the last time I'd seen him he's gotten married, has two kids, and has been nominated for a Nebula Award. From his blog you can find links to his biography and bibliography. I honestly don't know if he identifies as Muslim per se but some of his fantasy stories deal with Muslim identity in interesting ways. Its worth checking out.
