Charm and information share the stage in this easy informational book about hedgehogs. Their protective spines, nocturnal lives, and the raising of baby hoglets are all described, as well as the dangers they face from vehicles and badgers. The creatures’ diet, including wood lice, centipedes, and butterflies, is vital as they gain weight in preparation for their winter hibernation. A short final note states that none of the 17 species of hedgehogs are found in the wild in North America, and that it is illegal to keep them as pets in many places. Mixed-media illustrations showcase infinitely appealing hedgehogs (sporting an anthropomorphic smile) in their natural environment throughout the changing seasons. (Ages 4–8)
