What to expect

A pioneering marine biologist takes us down into the deep ocean in this 'thrilling blend of hard science and high adventure' (The New York Times)

Edith Widder grew up determined to become a marine biologist. But after complications from a surgery during college caused her to go temporarily blind, she became fascinated by light as well as the power of optimism.

Below the Edge of Darkness explores the depths of the planet's oceans as Widder seeks to understand bioluminescence, one of the most important and widely used forms of communication in nature. In the process, she reveals hidden worlds and a dazzling menagerie of behaviours and animals. Alongside Widder, we experience life-and-death equipment malfunctions and witness breakthroughs in technology and understanding, all of it set against a growing awareness of the deteriorating health of our largest and least understood ecosystem.

'A vivid account of ocean life' ROBIN MCKIE, GUARDIAN BOOK OF THE DAY

'Edie's story is one of hardscrabble optimism, two-fisted exploration and groundbreaking research. She's done things I dream of doing' JAMES CAMERON

'A book of marvels, marvellously written' RICHARD DAWKINS

Critics Review

  • A thrilling blend of hard science and high adventure

    New York Times Book Review

  • A vivid account of ocean life... Stylish, eloquent

    Guardian Book of the Day

  • Edie's story is one of hardscrabble optimism, two-fisted exploration and groundbreaking research. As I've said many times, I'd have wrapped my submersible, the DEEPSEA CHALLENGER, in bacon if it would have lured the elusive giant squid from the depths. In Below the Edge of Darkness, Edie tells you how she did it

    James Cameron

  • To shed light on a subject is what any scientific book should do. To go into it in depth without losing the reader is a harder task. Edith Widder's subject is light itself - the manufacture of light by strange and eerie denizens of the deep sea - and her scintillating style is worthy of it. This is a book to delight the general reader while simultaneously informing the professional: a book of marvels, marvellously written

    Richard Dawkins

  • My experience of exploring the deep ocean and its alien life with Edie Widder was fabulous. She enthrals us with many such stories in her book. I recommend it

    Ray Dalio

  • Personal and page-turning, adventurous and awe-inspiring, Below the Edge of Darkness sparkles with the thrill of exploration and glows with an urgent plea for the future of our precious seas. Comparisons to Jacques Cousteau spring to mind, as Edith Widder shares the profound journey of her life -one as unique and important as the unexplored realms of our very own planet

    Juli Berwald, author of Spineless: the Science of Jellyfish and the Art of Growing a Backbone

  • Luminous - the topic, the heroic journey, and the author herself. Dive in with Edith Widder, trail-blazing scientist and explorer, as she reveals the galaxy of light and life in the universe below the surface of the sea, out-shining sceptical male colleagues with dignity, grace and a robust sense of humour

    Beyond using Gfp to illuminate my bacteria in the lab, this is the first time I have read in-depth about bioluminescence. Beyond bioluminescence, this book correctly justifies the lack of funding for exploring Earth, our living, breathing planet. The expeditions, the wow-factors of finding something new - all are strangely nostalgic and resonate with my own experience working in microbiology.
    For people from non-Science background, I think this is a great introduction to marine life and the many hidden wonders. The Science is approachable. The author's personal experience have been woven wonderfully throughout the topics covered in the book.
    I thoroughly enjoyed reading this book.
