A New York Times-bestselling author's intricately conceived, "remarkably eloquent" response to Moby-Dick: a story of harmony between man and whale (The Washington Post). This unique adventure tale follows two characters: one a sonar officer aboard a sinking Russian nuclear submarine; the other a massive, aging sperm whale swimming nearby. As the young man spends what may be his last days with the ship's lovely surgeon, he listens to the plaintive calls of the whales sounding-calls of compassion, fear, and anger at humankind's attacks on his species. Little does he realize these fellow creatures may also provide his only hope of survival. Giving voice to these magnificent mammals, Hank Searls-who in addition to his work as a writer has also been a yachtsman, underwater photographer, and Navy flyer-taps into our ancient connection to the natural world in a fascinating, suspenseful, and provocative drama.
