Imogen Lovelace is an ordinary fangirl on an impossible mission: to save her favorite character, Princess Amara, from being killed off in the Starfield movie sequel. The problem is, Jessica Stone, the actress who plays Amara, desperately wants to leave the franchise behind.
When a case of mistaken identity at ExcelsiCon throws look-a-likes Imogen and Jess together, they quickly become enemies. But when the script for the Starfield sequel leaks, and all signs point to Jess, she and Imogen must team up and trade places to find the person responsible.
That's easier said than done when the girls step into each other's shoes and discover the darker side of fandom -- as well as unexpected romantic possibilities. Can these "princesses" find a way to rescue themselves from their own expectations and redefine what it means to live happily ever after?
