trialmeMary Losure writes innovative nonfiction (and the occasional fantasy) for kids.

Her books have been praised in The Wall Street Journal, Kirkus, Booklist, School Library Journal, and other publications. Her most recent one, Isaac the Alchemist: Secrets of Isaac Newton, Reveal’d (Candlewick, February 2017), received three starred reviews and was honored in “best of” lists for both science writing and nonfiction.

Before she began writing for children, she was an award-winning environmental reporter for Minnesota Public Radio as well as a freelance  contributor to National Public Radio.

Along with writing for kids, she also makes occasional appearances in the guise of a travelling alchemist. In 2018, she was honored to be invited to the amazing Gravity Fields Festival, a celebration of the life of Isaac Newton held every two years in Grantham, England.
