It was heart-warming book with plenty of fun facts and knowledge. I am very picky reader. However, I enjoy this book so much that I recommended to lots of people(which I have never done). I see how human damage the ocean and marine lifes. When I ordered the books as a set, the author gave me two poster showing all the species included in the books and another A4 paper showing the organisation to send each types of trash to. PS. I am in Thailand.
