Mike Mulligan and the Secret of the Magic Berries

Imagine a tale that has some of the wild improbabilities of a Harry Potter novel, all set in America's favorite national park, Yellowstone. In the sequel to Mike Mulligan, the Magic Eagle of Yellowstone, 14-year-old Nick now introduces his girl friend Geni to magic berries that allow them to shapeshift into various wild creatures and to communicate with them. Then imagine those improbabilities shaped by accurate natural history. Finally, lace that all together with exciting life-or-death struggles and a boy's kinship with an eagle named Mike Mulligan who makes all the magic possible.
