Enormous Big and tiny Little, two adorable dogs, go over and under, deep and shallow, in and out in pursuit of a butterfly. A simple book that introduces the important concept of opposites to the very youngest readers. Loveable Big and effervescent Little opposite in size--and the way they see and navigate the world--as they follow a butterfly. Their journey is told entirely through pairs of opposite words and gentle artwork, and it's full of surprises, including an unexpected run-in with a cranky bear. Fortunately, Big and Little get from here to there and safely home again, just in time for a well-earned rest. The charming narrative arc that runs throughout the story really sets this book apart from other "opposites" books.
