Into the Fire — James Collins

A first person thriller told by two narrators one of whom is lying. Mike is 16 and on the streets. Jack is 23 and trapped. Working for an illegal boy-brothel he is little more than a servant to William Sutherland. When he is forced to recruit Mike to this sleazy underworld he decides it's time to quit. He takes Mike and evidence of Sutherland's crimes and heads off across Europe to escape the contract killers now after them both. But nothing is what it seems, and we don't know who is telling the truth.
