chunk: He awakes in 2419 and, thinking that he has been asleep for just several hours, wanders for a few days in unfamiliar forests (what had been Pennsylvania almost five centuries before). He finally notices a wounded boy-like-figure, clad in strange clothes and moving in giant leaps, who appears to be under attack by others. He defends the person, killing one of the attackers and scaring off the rest. It turns out that he is helping a woman, Wilma Deering, who, on “air patrol”, was attacked by an enemy gang, the "Bad Bloods", which is presumed to have allied themselves with the Hans.
  Wilma takes Rogers to her camp, where he is to meet the bosses of her gang. He is invited to stay with their gang or leave and visit other gangs. They hope that Rogers’ experience and knowledge he gained fighting in the First World War may be useful in their struggle with the Hans.
