Once upon a time, in the 1970s, a lonely, imaginative boy met a mysterious, magical girl...and such began the most wondrous of summer quests. Benny Woodson is a boy of broad imagination, content to spend his days alone in the Indian Woods, exploring the forest on make-believe adventures, filling in a handmade map of his fantasy playland, which he calls The Mystic Grove. Benny's reality becomes intertwined with Native folklore and the realms of magic when he meets Katy Shepard, his unexpected and immediate best friend. Together they embark on the adventure of a lifetime, a mysterious summer quest to save the world, and all other worlds.
