Humans are the undisputed apex predators of our planet…but only on land. At sea, it’s another story altogether. Sharks are our last great enemy, and they’ve fascinated us from the time we were small children. Nature’s perfect killing machine has been quietly knifing through the icy deep teeth-first, murdering everything in its path on a nonstop bloody rampage that’s lasted for more than a hundred million years. (This is true: There were sharks before there were trees.) This fascinating deep dive into the world of sharks—the many varieties, their weapons and tactics, their social and mating behavior—will thrill and fascinate readers of all ages. You may never go back into the water again.
