Janine Prentiss, a twelve-year-old Native American girl, is tired of spending her summers digging up dinosaur bones with her single-parent father, an eminent paleontologist. But neither does she want to spend her summer vacation listening to her shaman grandfather’s lame tales of spirit quests and totem creatures who talk. Instead of messing about with dead bones or fairy tales, Janine wants to go to cheerleading camp with her best friend. She wants to be a normal girl! Unfortunately, Dad doesn’t consider cheerleading a legitimate use of her time or his money. Bummer.
Justin Prentiss thinks his twin sister is nuts. What kid in their right mind wouldn’t love field camp? The wild beauty of Montana mountains, fresh air, and adults too busy to pay attention to what a guy is doing as long as he shows up for meals and bedtime. Field camp rocks!
However, it isn’t Justin who is drawn to the mysterious rock. It’s Janine, and the idiot girl is convinced that the chunk of granite–a fossil at best–is a real, live egg and that she’s got to protect it while it hatches. Girls!
The discovery of the thunderbird egg sweeps Janine and Justin off on the adventure of a lifetime. Not only will they discover that thunderbirds exist, but they’ll come face to face with malicious evil in the form of Unktehi, a spirit of disruption straight out of their grandfather’s legends.
