COSine Science Fiction Convention

January 22-24, 2016

COSine would like to thank all of the participants and attendees for 2015, most especially our Guest of Honor, Nathan Lowell, our Science Guest, Wil McCarthy, and our Special Guests Connie and Courtney Willis. We had a very successfull convention, with over 220 people in attendance! This was our 11th year running COSine, and we are pleased to have had such great attendance after taking a necessary year off in 2014. Thank you all for coming!

Our artists did well with sales this year, and we had fun knocking down boxes and dancing at our Angry Birds live game and dance. The author reception was very well attended, and we had busy program and gaming rooms throughout the weekend.

COSine 2016 is pleased to announce that our Guest of Honor will be Jim Butcher!

Author of the well-known Dresden Files series, as well as the Codex Alera, and a new steampunk series, the Cinder Spires. We are excited to have Jim as our guest in 2016. More information will be coming, check here or our facebook page for updates!

COSine 2016 information will be coming soon! COSine has a membership fee that includes all activities and our renowned Con Suite with food and drinks you can enjoy all weekend.


COSine is proud to feature Jim Butcher as our Guest of Honor for 2016. More information will be forthcoming.


COSine 2016 will be returning to the same hotel we have used in the past, now called the Hotel Eleganté Conference & Event Center, located at the south end of Colorado Springs, just off I-25. The hotel has great function space for our convention, and the best view ever from the dealer's room!
