October K Santerelli:

Fantasy author

October K Santerelli is an author, LGBTQ+ sensitivity reader, and international speaker and presenter who calls Denver, Colorado ‘home.’ His works span several genres, including fantasy, historic romance, and science fiction. He writes for multiple age groups, having in the past written for young adult and adult audiences. Santerelli has written in multiple formats, creating everything from novels, novellas, and short stories to comic scripts and video games.

His career began with training the dog of a best-selling author, and led through one networking opportunity after another until he was introduced to award-winning author David Brin. His first published novel was STORM’S EYE, in Brin’s Out of Time universe. It was also his first science fiction piece.

His second work, CITY OF DAY, released in February 2023 and was the first book of his debut fantasy trilogy, the Nightfall series. The cover won GoIndieNow's Cover of the Year 2023, and the book itself made their Indie Dozen list of top reads. The second in the series, CITY OF NIGHT, was released with a Barnes and Noble launch party in February of 2025.

Santerelli has spoken to numerous organizations, podcasts, youtube channels, and more — notably for his work as a sensitivity reader for the LGBTQ+ community, on the creative process for persons who are neurodivergent, and on writing craft. He has spoken to several branches of the Romance Writers Association (RWA), served as a Science Fiction/Fantasy Writers Association (SFWA) mentor, and been a guest, attending pro, and/or panelist at multiple conventions. He has been on over one hundred panels, and run more than fifty workshops.

An avid creator, when he is not writing novels, comics, short stories, novellas, or video games, Santerelli can be found painting with the traditional media of watercolors — including creating fantasy maps with watercolor and brush pens, such as the one found at the beginning of CITY OF DAY.

Recently, Santerelli has left the United States and moved to Berlin, Germany for several years of writing and research - namely in the realm of castles, the Brothers Grimm, fairy tales, and Germanic middle history. His adventures are being documented on Youtube, and shared in both his newsletter and on his Patreon.
