The story follows the unlikely friendship of two young women forged via fan fiction and message boards, and is told entirely in texts, chats, and blog posts. Gena (short for Genevieve) and Finn (short for Stephanie) have little in common. Book-smart Gena is preparing to leave her posh boarding school for college; down-to-earth Finn is a twenty-something struggling to make ends meet in the big city. Gena’s romantic life is a series of reluctant one-night-stands; Finn is making a go of it with long-term boyfriend Charlie. But they share a passion for Up Below, a buddy cop TV show with a cult fan following. Gena is a darling of the fangirl scene, keeping a popular blog and writing fan fiction. Finn’s online life is a secret, even from Charlie. The pair spark an unlikely online friendship that deepens quickly (so quickly it scares them both), and as their individual “real” lives begin to fall apart, they increasingly seek shelter online, and with each other.
