Summary

Mary is a plain, young girl, stuck in a rural British village with her Great-Aunt Charlotte and seemingly no adventures or friends in sight. But a chance encounter with a pair of mysterious cats leads Mary into the nearby forest, where she finds an old broom stuck in the overgrowth of a nearby tree, and the strange blue glow of the fly-by-night flower, a rare plant that blossoms only once every seven years. As the broom comes to life and lifts Mary high into the skies, she discovers a mysterious school for witches above the clouds. But the charming headmistress Madam Mumblechook and bumbling Doctor Dee are not all that they appear, in a twisting tale that reveals even the most ordinary-seeming children are capable of the most extraordinary adventures.
