A host of nature lovers throughout America, children and adults, await each new Sam Campbell book about his experiences with animals. The Seven Secrets of Somewhere Lake is one of the best that has 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. Although they look forward to the experience, they realize it means leaving their island Sanctuary deep in the north woods of Wisconsin. 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. The Campbells 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 the four assorted Z's aren't enough, seven young beavers are literally dumped into Sam's lap.
