For decades children and their parents around the world have cuddled together to read Goodnight Moon and The Runaway Bunny. While the lulling words of these stories have formed nighttime rituals for millions, few know that these classic works were part of a publishing revolution led by Margaret Wise Brown, who was renowned not only for her prolific writing and creative genius, but also for her stunning beauty and thirst for adventure.In 1990 author Amy Gary discovered unpublished manuscripts, songs, personal letters, and diaries from Margaret tucked away in a trunk in the attic of Margaret's sister's barn. Since then, Gary has pored over these works and with this unique insight into Margaret's world she chronicles her rise in the literary world. Clever, quirky, and wildly imaginative, Margaret embraced life with passion, threw wild parties, attended rabbit hunts, and lived extravagantly off of her royalties. She carried on long and troubled love affairs with both men and women, including the ex-wife of John Barrymore, and was engaged to a younger man, who was the son of a Carnegie and a Rockefeller, when she died unexpectedly at the age of forty-two.In the Great Green Room captures the exceptional spirit of Margaret whose unrivaled talent breathed new life into the literary world.
