Hejsa's pursuit of extreme sports oddly brought her love of writing into focus. Her first published article was on the Eco-Challenge race she did in Fiji with her brothers. She has since published articles about trekking the Amazon, crossing the Atlantic on a yacht (once in a hurricane), competing around the world in taekwondo, and other adventures. She is much safer focusing on writing novels with her mother. She holds an MA in environmental geography and an MFA in creative writing from UBC, where she won the Random House/Hazlitt Award. In 2017, she was shortlisted for the EVENT Magazine Non-Fiction Contest.

She lives in Port Perry, Ontario with her husband, Giles, daughter, Taia, their dog, and various chickens and ducks.
