COSine Science Fiction Convention

January 22-24, 2016

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

Jim Butcher is the best-selling 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.

Announcing Bryan and Baxter as our Science Guests of Honor!

Bryan and Baxter are wildly entertaining, giving you the truth behind the stories of paranormal claims. With over 25 years of experience they've seen it all, and they're here to show (and tell) you all about it.

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!
