Journalist and San Francisco Grottoite James Nestor reads from his new book, Deep: Freediving, Renegade Science, and What the Ocean Tells Us About Ourselves, for which he learned to freedive and traveled to Honduras (where the laws aren't as strict) to take a DIY submarine as far down as -2,500 feet, past the point where light no longer penetrates the water. As David Epstein points out in his New York Times review of the book, "There is a point about 30 feet below the surface that freedivers know as 'neutral buoyancy.' Beneath it, the ocean stops trying to spit you out and begins sucking you in," and, "Whenever a net is dropped below 3,000 feet, a majority of species dragged up with it have never been seen before." Deep goes progressively further into the ocean, with the final chapter reaching depths of more than -28,000 feet, where life on Earth may have begun. Booklist, in a starred review: "With a 'wow' on every page ... Nestor's Deep is galvanizing, enlightening, and invaluable." Nestor is the author of Get High Now (without drugs), which Chronicle Books published in 2009.
