Cowboy Up! is a mix of poetry, narrative, and lots of excellent photos of Navajo rodeo. Children rope and ride, too, though on a tamer, and smaller scale. The photos are so good you can almost taste the dust.
The Mystery of Darwin's Frog tells about an unusual species where the daddy frog holds tadpoles in his vocal sac until they get their legs and are ready to see the world. It's written by a scientist who studied these frogs - and the illustrations are wonderful.
In addition to books, we've got some EXPLORE bags for the 8 and older crowd. One contains a handlens - perfect for searching out disgusting bugs and plants.
