What’s underneath? If you ever looked at a blue surface wondering about its hidden depths, or dreamed watching Blue Planet, you’ll love this book.

Under the Ocean follows the voyage of Oceano, a red sailing boat, from port to a tropical lagoon, through temperate seas, the great white Arctic and an oceanic storm. Each pop-up page plays on the idea of the sea surface as a border to be crossed, showing the two worlds ‘above’ and ‘below’ the water.

As for their previous books, Popville and In The Forest, the strength of Anouck Boisrobert and Louis Rigaud is not in the mechanics of paper engineering, but in the design of the page as a truly 3D space.

This delightful little book’s sense of adventure and discovery will make you look at every detail of ‘what’s underneath’ in a round-eyed kind of wonder – and yearn to dive in.
