While spending the last weeks of summer with her Great-Aunt Charlotte in the countryside, Mary follows a mysterious cat into the nearby woods. There she stumbles upon a flower that has magical powers and transforms a little broomstick into one that flies. Mary is whisked away, high above the clouds, and transported to Endor College – a school of magic!
Mary is warmly welcomed by headmistress Madam Mumblechook and the brilliant Doctor Dee. Believing her to be a “once-in-a-century” magical talent, they give Mary a guided tour of the dazzling school and invite her to join. But Mary discovers that all is not as it seems in this fantastical world, and soon must confront great danger and call on her courage if she is to save the day.
