Science Fiction Convention
COSine is a literary-focused science fiction convention that has been running in Colorado Springs since 2004. It is run by First Friday Fandom. While we enjoy TV, movies, games, and comics as much as the next science fiction and fantasy fan, we wanted to keep the focus on the books and stories that first captured our hearts and drew us to the genre.
