831 Stories is building a book brand for the fandom obsessed.

Jul 25 2025

831 Stories is building a book brand for the fandom obsessed. Founded by Claire Mazur and Erica Cerulo, the company goes beyond just publishing romance novels and letting the fandom create itself. They’re creating merch and even commissioning fanfiction of their titles to be embedded in the community—because if there’s anything to know about #BookTok, both will exist eventually.
