The author, Rieko Nagakawa, is known for her children's works, and her warm illustrations enhance the stories. This book is aimed at toddlers to lower elementary school children, and can be enjoyed by parents and children together. Recommended for children who like Guri and Gura. "Sora-iro no Tane" (Sky-Colored Seed) has a stain from a black color pen in one place. Please refer to the second photo. The other pages, as far as a casual inspection goes, have no stains or tears.
