Synopsis

Cassie's online life revolves around writing vampire fanfiction for her favorite show, complete with a glamorous original character of her own creation. When her secret writing gets exposed at school, the fallout goes from merely awkward to genuinely bizarre: her fanfic OC walks out of the page and into her actual life.

As Cassie and her friend navigate the consequences, both social and supernatural, they're pulled into "Mary Sue World," a strange space built from the archetype fanfiction writers love to mock, and come face to face with the original Mary Sue herself. The series uses its central gimmick to gently interrogate fandom culture, the stigma around "self-insert" characters, and the real friendships that online creative communities can build.

Written by Meghan Fitzmartin and illustrated by Lisa Sterle, this BOOM! Studios miniseries is a warm, funny coming-of-age story about fandom rather than a straightforward romance.
