Our take
AI-draftedCasey's real subject isn't the ocean floor so much as the gap between how little we know about it and how much we're already doing to it—deep-sea mining, industrial fishing, warming water—and she makes that argument by embedding herself in submersibles alongside the scientists and engineers doing the diving. The implicit comparison she keeps drawing, that the deep ocean is a more urgent and more poorly funded frontier than outer space, is the book's most persuasive throughline.
In the press
“One of the most accurate and vivid portrayals of a deep-sea dive that I have ever read.”
Science“Casey's book satisfies our greatest curiosities about the mysteries of the ocean.”
