Sisters in Crime-Colorado is an organization run completely by volunteers and we strive to have every single member involved.
Every member of SinC-CO has expertise, whether they believe it or not! We firmly believe in the "one hand forward and one hand back" philosophy. No matter where you are in your journey, you can help someone and you can receive help from someone.
Our members include men and women, best-selling authors and aspiring authors, short-story writers and series writers, and some of us aren't primarily writers at all - we include a voice actor, an author website creator, a mystery book blogger and more!
What we share is a love of mystery reading and writing in its many forms and genres. If that describes you, join us!
Show up for events!
It's simply impossible for you to attend a SinC-CO event without learning something useful while enjoying the company of like-minded individuals.
Check the Activities page to see all the opportunities we offer. Make the time to invest in yourself and have a bit of fun while doing so.
Stay connected!
Keep up with us to see how our members navigate writing, publishing and marketing to get our books in front of readers. We learn from each other!
Check the Connect page to see all the ways we share what we're doing, from a private chat group to social media to a monthly newsletter open to all.

You don't have to be a published author or a longtime member to volunteer your time and talent to make our chapter even stronger and more vibrant.
