Susan Arnold fell in love with the world of writing at the young age of eight when she began writing a story about a girl named Vicka Nicky Nay. Five years later, her eighth-grade English teacher gave an assignment that changed her life; which was when she began writing Blue Vigilante. After another five and a half years, Arnold enrolled at Northern Michigan University to pursue a degree in both English Writing and Photography. She self-published Blue Vigilante in May 2016. She graduated from NMU in May 2019.
In August of 2019, Arnold published a photo book with the portraits of sexual assault and abuse survivors, paired with their transcribed stories.
Currently, Arnold is attending Missouri State University as a full-time graduate student. She is also working on the second book in the Vigilante Series, Green Vigilante.
