Feeling like an outsider in a new city and at a new school, Mariam finds that her love of comic-book superheroes overlaps with the interests of a new friend who is otaku, crazy about manga and anime. Together, Mariam and Tya plan their costumes for the big fan convention. Mariam is comfortable with her choice of character, partly because as Haruhi, she can dress in a costume that doesn't bare too much skin.

When Tya can't go to the convention, Mariam is relieved to meet up with some boys who are dressed as the rest of the group from Haruhi's manga. Rick, dressed as Haruhi's love interest, insists that Mariam spend all her time with him, doing things that their characters like to do and playing out their romance. When he tries to physically force himself on her, Mariam realizes that Rick is taking the game way too seriously, but how can she escape his attention?

This novel explores the appealing world of comic books and graphic novels that has growing numbers of young people exploring role playing and attending fan conventions.
