"A plan began clotting in what our biology teacher called Wetware--my brain. What if I went to Concho Mountain and confronted the Ancient? What if I gave every stinking piece of old history back and ordered him to leave? Was that normal thinking . . . me hashing it out with someone that almost didn't exist?"

Silki, A young Navajo girl, thought she'd made up Wol-la-chee, the Ancient Ant Man, on one of her horseback rides with her best friend Birdie. When Wol-la-chee shrieks into her life one summer day on Concho Mountain, Silki's world turns upside down. With her family pushing her toward more responsibility and respect for her heritage, how can Silki find the time to solve this new and frightening mystery? If Birdie thinks Silki has gotten her real and unreal mixed up, will that push the two girls apart or bring them back together?
