Halfway across the country, Mark Monday moves to Colorado. Up until now, his life has not gone well. He is blind in one eye and extremely weakened by rheumatic fever. He is also somewhat of a loner, a result of having moved every two or three years of his life. In what will prove to be a life-changing event, Mark befriends Juan, a Tom Sawyer-like boy with endless self-assurance and an unerring ability to get into trouble.
Between the three stands Elfleda, a 1,600-hundred-year-old Angle princess, forever trapped by alien technology in the body of a 15-year-old. Only she can bring the teens together and only they can save the Earth from an ancient warlord who will wreak devastation and death upon millions.
