520    A pioneering marine biologist takes us down into the deep 
       ocean to dunderstand bioluminescence--the language of 
       light that helps life communicate in the darkness--and 
       what it ells us about the future of life on Earth. Edith 
       Widder's childhood dream of becoming a marine biologist 
       was almost derailed in college when complications from a 
       surgery gone wrong made her temporarily blind. Her new 
       reality of shifting shadows drew her fascination to the 
       power of light--as well as to the importance of optimism. 
       As her vision cleared, Widder found the intersection of 
       her two passions in oceanic bioluminescence, a little-
       explored scientific field within Earth's last great 
       unknown frontier: the deep ocean. With little promise of 
       funding or employement, she leaped at the first 
       opportunity to train as a submersible pilot and dove into 
       the darkness. Widder's first journey into the deep ocean, 
       in diving gear that resembled a suit of armor, took her 
       down to eight hundred feet. Turning off her lights, she 
       witnessed breathtaking underwater fireworks: explosions of
       bioluminescent activity. Her concerns about her caerer 
       vanished. She only wanted to know one thing: Why was there
       so much light down there? Below the Edge of Darkness takes
       readers deep into our planet's oceans as Widder pursues 
       her questions agout 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 beaviors
       and animals, from microbes to leviathans, many never 
       before seen or, like the legendary giant squid, never 
       before filmed in their deep-sea lairs. Alongside Widder, 
       we experience life-and-death equiment malfunctions and 
       witness breakthroughs in technology and understanding, all
       set against a growing awareness of the deteriorating 
       health of our largest and least understood ecosystem. A 
       thrilling adventure story filled with scientific 
       revelation, Below the Edge of Darkness reckons with the 
       complicated and sometimes dangerous realities of 
       exploration. Widder shows us how when we push our 
       boundaries and expand our worlds, discovery and wonder 
       follow. these are the ultimate keys ot the coea's 
       salvation--and thus to our future on this planet--From
