I really enjoy coloring to relieve stress and this book has been extremely helpful. The pages are beautiful and unique while staying in the Manga style of art. This book has mermaids, sea creatures, and winged creatures all accompanying Manga humans. Along with the beautiful coloring pages it has quite the cute introduction that I won't spoil for you.
I do suggest this book to any colorists out there. The only downfall (which isn't truly a downfall) Is that it doesn't have the repetition of pattern that some colorists look for. Instead, it is a unique piece of art on every page.
