How about the book "The Emerald Mile" by Kevin Fedarko? It tells the story of a historic and epic white water rafting journey through the Grand Canyon. Additionally, you could gift her a rafting trip or a gift certificate to a local rafting company, so that she can plan a trip with her friends or family. Another great gift idea could be a waterproof camera that she can use to capture and share her exciting rafting experiences.
Or you can get her a star map with an important date you share.
