“…Mercer’s prose is lucid and her themes of redemption and reinvention are resonant…”

J Mercer grew up in Wisconsin where she walked home from school with her head in a book, filled notebooks with stories in junior high, then went to college for accounting and psychology. She is a member of the Society of Children’s Book Writers and Illustrators, wishes she were an expert linguist, and enjoys exploring with her husband and daughters. Perfect days include cancelled plans, rain, and endless hours to do with what she pleases.
