A book featuring fun illustrations and stories with a Shiba Inu theme. Set of 4 books. "Gon and Tets's Sunny Days" has a stained cover. - Author: Naomi Kageyama Thank you for looking. I love cats, but I also liked Naomi Kageyama and collected the Shiba Inu series. The illustrations are gentle and soothing. These are my favorite books that I've read many times. There are some stains, so please refrain from purchasing if you are looking for a perfect copy.
