Guess Who Again? is a beautifully illustrated autumn book, richly colored with the hues of fall foliage. Photos of maple leaves, ginkgo leaves, oak leaves, and other colorful leaves combine with collages of varied textures to create a vivid, abundant portrait of autumn. Like its predecessor, this is a two-beat guessing picture book featuring animals whose faces are hidden behind leaves, but overall it's a bit more challenging. Unlike the previous book, which was designed so children could guess the answer intuitively, this one is written so that readers piece together clues in the pictures step by step to arrive at the answer. It's designed to help young readers focus on the process of observing and reasoning as they look at the pictures.
