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.
