Princess Addison (Addy) is sent as a peace offering from her home country of Addleburrow to the military powerhouse and “traditional moral beacon” nation of Provincia. There she’s greeted by the self-hating, closeted yet charming King Victor, who introduces Addy to her betrothed, the oafish yet lovable Prince Dimitri. But Addy takes far more notice of Dimitri’s sister—fiercely rebellious Princess Dahlia, who stands opposed to the moral standards her father Victor imposes on his citizens and also closeted daughter, but is powerless to fight against him. Addy immediately falls for Dahlia, but knows if the king catches her acting any less “traditional” than a medieval June Cleaver, he’ll retract the peace between Addleburrow and Provincia, and her nation will suffer a crushing military defeat.
Through the help of her bodyguards Eric and Ella, her new friendship with the ever-loyal Dimitri, and fairy godfather Gary (who is both a fairy and a “fairy,” a gay man, but come on, he’s heard that joke hundreds of times before) Addy and Dahlia’s love overcomes Victor’s bigotry, Dahlia’s hesitance to come out to herself and others, Provincia’s standards of normalcy, and a poorly-catered wedding party.
