Kendall can't believe how quickly his dad remarried after his morn died, and he especially can't believe his dad's choice: Juanita is of Spanish descent. That feels like a slap in the face considering Kendall's mom was Native American. This is all more than Kendall can handle, and he needs to get away to the desert where he can think. And especially where he can run. Running is his destiny: he's the last member of the Snake Clan, the clan known for its long runs across the desert floor -- until the Spanish arrived in the Southwest and destroyed the tribe.When Kendall slips through a hole in time, he finds himself 400 years in the past, just as the Spanish, with their guns and armor, are starting to lay claim to the Southwest. Can Kendall survive the horrible battles so he can return to his own time? Will he become the last Snake Runner, as the spirits have told him he must? More importantly, what will he learn about himself in the process?
