Fourteen-year-olds Lisa and Roper are about to have the adventure of a lifetime. When their friend, Mattie, sends them into the desert to look for old pictures -- called petroglyphs -- on rocks, they have no idea how valuable they might be. Then the petroglyphs start disappearing. And soon the trees are missing as well. Lisa and Roper know they have to do something about it before it's too late. Set in present-day Arizona, Lisa and Roper are aided in solving this incredible mystery by Lisa's eight-year-old cousin, banana eating butterflies, a demanding raven and even a steer named Hercules. A fast-paced adventure for young adult readers.
