Marcus Caster-Rupp is known to the world as Aeneas, his character on TV's biggest show, Gods of the Gates. But secretly, he's "Book!AeneasWouldNever," a fanfiction writer who ships Aeneas and another character, Lavinia. April is a hardcore Lavinia fan, but when her plus-sized cosplay goes viral, online trolls attack. Attempting to defend her, Marcus asks April out, but quickly realizes he wants a real relationship with her — especially once he finds out she's actually "Unapologetic Lavinia Stan," his closest fandom friend. But with so many secrets, can Marcus ever truly reveal himself to April — and to the world?
