8 brilliant books about the Deep Blue Sea

Book Adventurers | Published: 26th July 2021

Earth's oceans and seas are vast and still predominantly a mystery to humankind. Here are 8 brilliant book choices that aim to solve some of that mystery as well as weaving wonderful stories inside these magical kingdoms.

Oceans and seas cover over 70% of the earth’s surface,  yet only 5 percent of this vast expanse has been properly explored. While that keeps much of the underwater world deliciously mysterious, it also manages to prick the curiosity of children and adults alike. Whether we’re exploring rock pools at the beach, or watching David Attenborough documentaries our interest seems only to grow and grow.

Earlier this month we focussed on our top picks for our book club – The Blue Giant and Ocean Meets Sky, and today we’re sharing even more marvellous tales and revelations set in, and about the Deep Blue Sea. We hope you like them!
