In case you haven't heard, there's a new website devoted to Christian speculative fiction. Aptly titled Where The Map Ends, the site was started by Jeff Gerke. Jeff has written several novels (including the Operation Firebrand series) and was an editor with Strang (he helped start the Realms imprint) and NavPress.
There's lots of great stuff at the site. Interviews, tools for writers, and most recently a collaborative fiction project has been announced. Especially helpful is a Booklist featuring science fiction and fantasy titles in the Christian market.
