When the lights go out in Mary's bedroom, everything changes. The bookshelf becomes a tower, the bed turns into a mountain, and the closet transforms into a castle where her stuffed animals come to life. But one night, a terrifying creature called the Bumblegruff appears and even the bravest toys are too afraid to face it. Enter Micah Mouse, a humble musketeer in the Queen's Guard. Though he's small and untested, he steps forward when the knights shrink back. Armed with nothing but courage and cleverness, Micah must confront the monster under the bed and protect the kingdom when no one else will. Sir Underbed is a richly illustrated, longer-form picture book that blends imaginative adventure with timeless lessons about bravery, humility, and standing up for others. With humor, heart, and just the right amount of suspense, this classic-style tale will captivate young readers and become a family favorite. Ideal for children ages 6-9, it's perfect for bedtime, classroom read-alouds, and character-building discussions.
