Jen Fier Jasinski spent much of her childhood reading books and imagining new worlds. Unwilling to let go of Story Time, she grew up to become a teacher, mother, and author. Now Jen writes stories with elements of humor, heart, and above all, play. She is the author of My Piano (2023), Sidewalk Chalk (2025), My Violin (2026) and Because of You, I’m a Sister (2026). Because of You, I’m a Sister was an instant national bestseller featured on the USA Today Best-Selling Booklist. My Piano earned a starred review from School Library Journal.
When she’s not writing, Jen can be found with her spouse and kids, running, or playing outside. Her favorite days are when she gets to do all three. Her extra favorite days include cake.
