When Halley's comet arrived in 1910, so did an extraordinary person: Margaret Wise Brown. Margaret had a boundless imagination and a gift for spinning stories. Most grown-ups thought children's books were frivolous and silly, but Margaret didn't agree. Could writing stories for children be important work--a incredible way to share truth, beauty, and wonder? Other people might call Margaret strange, and sometimes her own worries and doubts felt overwhelming. But only Margaret and her original ideas could lead to Goodnight Moon, The Runaway Bunny, and other classics beloved by children around the world. From smuggling rabbits onto trains, to scribbling stories about island whispers, Margaret embraced adventure in life and on the page. This whimsically illustrated biography shares how an independent, fun-loving woman became a trailblazing pioneer of the picture-book form.
