[32][33] In interviews, McQuiston has expressed hopes that Red, White & Royal Blue, along with their future novels, will help push queer romance into the spotlight.

[34] Additionally, many of the characters in Red, White & Royal Blue were inspired by different political ideologies and archetypes instead of real-life people.

[4] The book is "pitched as a queer Kate & Leopold, in which a 23-year-old realizes her subway crush is displaced from 1970's Brooklyn, and she must do everything in her power to help her - and try not to fall in love with the girl lost in time - before it's too late.

The subway quickly becomes August's favourite part of her day and she realizes that she needs to do everything in her power to help return Jane back to her own time before it is too late.

McQuiston states "I always thought it was silly and unrealistic, the idea that some straight people have, that it is statistically unlikely for more than one gay person to exist in the story.
