This book is stunning, captivating, and exquisitely beautiful. From the rich surreal illustrations to the brilliant prose. It takes us on a young girl’s journey as she learns what it is to love.

The author weaves a magickal tale with the vision to educate, teach reverence, and respect for the ocean and its inhabitants. He instills a sense of wonder while explaining the interconnectedness of our actions on the planet.

Not only is it written for children, but as an adult, I found it provocative in exploring deeper meaning. This book is absolutely inspiring and has deeply touched my heart. It is amazing and one of a kind. With my whole being, do I highly recommend this incredible work of art.

This book has some of the most beautiful artwork I have seen in a picture book. It looks to be influenced by the Japanese colorful style of tattoo work, the ones depicting legendary characters. The colors are fantastic.

It's a cute story. The art is very beautiful, though the eyes on the bunnies were a bit scary to me. I loved the sea creatures the most, they were beautiful illustrated.

I’m very convicted and the poetry is lovely~

They lost me a little bit at the illustration with the tentacles but that’s just because I’m not innocent. This would be cool for a kid~

A feast for the eyes. I almost considered buying a copy because the illustrations are both beautiful and just slightly unnerving. They're incredibly rich, and the story is dense as well.

Sublime illustrations. I love them so much and have them sitting on the coffee table for regular flip throughs.
