Nikki Castle

Nikki Castle

Nikki Castle is a wife and dog mom from Philadelphia who writes spicy love stories about alpha MMA fighters and the women that melt their badass, playboy hearts. She's a full-time romance author during the day and spends her evenings running a Mixed Martial Arts (MMA) gym with her husband, who is also a retired fighter.

Nikki has been writing in one way or another since she was a teenager. She pursued an English and Philosophy degree in college, and finally decided to sit down and fulfill her longtime dream of writing a novel when quarantine began in 2020. “5 Rounds” was her first book—and it was supposed to be her only book. Now, she’s a full-time author who can’t imagine a life in which she’s not crafting love stories.
