Scott and Emma's first collaboration was inspired by a favorite hike on the Appalachian Trail in northern Georgia. As they passed a hollow tree, Emma asked aloud, "I wonder who lives in that tree?" Scott's answer: "Hey, that sounds like a book title." Several off-the-cuff rhymes later, their book was underway. Beautifully illustrated in watercolor, this simple, rhyming tale will please parent and child alike. A surprise at the end is sure to delight again and again.
