Time Riders: Day of the Predator is a classic example of the “book for boys” which has become a kind of brand: easy to identify and equally easy to dismiss as likely to be fast-paced, action-packed, competently written, and not terribly original or interesting. Alex Scarrow has written the best young adult science fiction novels since Robert Heinlein was producing ‘juveniles’ like Citizen of the Galaxy. Time Riders: Day of the Predator – the second in a series which begun with a resuscitated Nazi Germany using flying saucers – has the ingenious concept of time agents, who are trying to stop history from being destroyed, functioning from a time-bubble base that hides by endlessly experiencing the same two days in New York: the 10th and 11th of September 2001. The agents themselves are young people recruited from unexpected disasters – crashing planes and collapsing buildings – so they are never spotted as missing.
