Meet 25 female explorers and scientists in these inspirational and poignant stories of exploration, courage, and girl power.

Along the way, they share lessons learned and words of wisdom sure to inspire the next generation of scientists, adventurers, and world-changers.

Track a volcanologist as she braves the elements atop an active volcano. Travel alongside a mountaineer as she battles stereotypes--and frostbite--to conquer the famed Seven Summits. Join a conservationist on her passionate fight to save lions. Dig with a paleontologist to uncover massive dinosaur fossils, bit by breathtaking bit. These heartfelt stories give readers an insider's look at the amazing work female explorers at National Geographic--and beyond--are doing in the field to solve some of the world's toughest problems.

Rather than detailing the lives of well-known women, this anthology celebrates lesser-known changemakers and outstanding women of diverse backgrounds, nationalities, and fields of study who are just beginning to make a name for themselves. Each profile is based on first-person interviews and comes paired with useful tips and relatable advice for budding explorers and scientists. Stunning photography and fascinating general interest information about the animals, places, and practices add drama and context.

No Boundaries sends a positive message to every girl who has ever dreamed or dared to go a little further. And although these explorers' endeavors are quite adventurous, the lessons they share can inspire all girls, as well as boys, whatever their goals, skills, and interests.
