"In this unique, breathtaking picture book, YOU are a narwhal--the unicorn of the Arctic! You joust, tusk to tusk, with another narwhal. You use echolocation to hunt for fish. You travel throu leads (small cracks) in six feet of ice in the Arctic Ocean. And--all while evading the jaws of hungry orcas--you migrate with your pod along a centuries-old path to your summer home."--Front jacket flap.
