Book excerpt: The Seven Secrets of Somewhere Lake is one of the best books that have come from the pen of this popular author, photographer, lecturer and naturalist. In the summer Sam and Giny plan to make a movie film of the Grand Canyon country. This year, they say, there are to be no baby animals taken in to be cared for. No sooner do they make this resolve than fate dooms it, with several large snickers. They have no choice but to adopt in rapid succession: Zipper, a half-starved fawn; Zowie, a baby red fox; Zanie, a taffy-colored puppy, and Zinnia, a tiny skunk! Then, as if that isn't enough, seven young beavers are literally dumped into Sam's lap.
