Want to attend?
COSine has a membership fee that includes all activities and games, Dealer's Room, Author's Reception & Signing, and our renowned Con Suite with food and drinks you can enjoy all weekend.
COSine is proud to feature Jo Walton as our Guest of Honor for 2017. Our Science Guest is magic laser man Jon Singer. We are pleased to again welcome Connie and Courtney Willis as our Special Guests.
COSine 2017 will be returning to the same hotel we have used in the past, 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!
Call for Volunteers!
Want to help out? We would love to have you! If you would like to lend a hand, contact the committee member in charge of any area you are interested in, or you can volunteer at the convention itself. You can come to meetings of First Friday Fandom to see how we organize the convention and share your opinions.
