Gone Is Gone looks at why species become endangered, how scientists are learning about endangered wildlife, what people are doing to conserve species and ways young people can help.

The book is richly illustrated with unique photos that the author has taken over many years of observing endangered species in the field alongside the people who work to conserve them. Throughout the book the author shares enchanting encounters and personal field stories: watching narwhals socialize in the Canadian Arctic, getting close to a Laysan albatross raising chicks in a remote Hawaiian island, spotting a rhinoceros on safari, and even swimming with sea lions in the Galapagos Islands.

Gone Is Gone will inform, intrigue and inspire readers to take small steps toward big changes for endangered species around the world.
