Gena and Finn would have never met but for their mutual love for the popular show Up Below. Regardless of their differences—Gena is a recent high school graduate whose social life largely takes place online, while Finn is in her early twenties, job hunting and contemplating marriage with her longtime boyfriend—the two girls realize that the bond between them transcends fanfiction. When disaster strikes and Gena's world turns upside down, only Finn can save her, and that, too, comes with a price. Told through emails, text messages, journal entries, and blog posts, Gena/Finn is a story of friendship and love in the digital age.
