This book has beautiful and colorful illustrations that are engaging. The story contains a clever mouse who uses his intelligence to keep from being eaten. The concept of animal homes is introduced to children. I like the fact that the mouse avoids violent conflict by using his wits. By the end of the story, the big, scary Gruffalo is the one you want to feel sorry for and to become his friend. I look forward to reading the other books with the Gruffalo as a character. I think the advertized age range of grades k-3 is appropriate for this book.
