Spoiler Alert

Marcus Caster-Rupp plays Aeneas on the most watched show on television, but in the online fandom he is known only as Book!AeneasWouldNever. Under that alias he vents his frustrations with the series by writing stories about Aeneas and his on-screen partner, Lavinia, the fans' favorite pairing. Exposure would cost him his place in Hollywood, so he guards the secret closely.

April Whittier loves Lavinia just as much, but she has kept her fanfiction writing and cosplay hidden from the people in her everyday life. That changes when she posts a costume she built for the character, a plus-size reimagining that spreads widely across Twitter. Marcus, stung by the criticism his online persona has drawn, asks April out to deflect the attention, and the date turns into something far more meaningful than a publicity move.

Marcus soon finds he wants more than a single staged outing. He also learns that April is Unapologetic Lavinia Stan, one of his closest friends in the fandom, which means he now has another major secret to keep from her. With his career and a new relationship both at stake, the two must decide whether they can finally stop hiding, or whether their romance will be cancelled before it has a chance to find its footing.
