TIMERIDERS

Time travel has become a reality in the future—but it becomes a dangerous reality when a megalomaniac decides to travel back to 1939 and tell Adolf Hitler how to win World War II. Imagine the invasion of the White House by Nazi storm troopers in the 1950s…or Times Square 50 years after surrendering to fascist rule…or a devastated world populated by cannibalistic mutants, which are all that remain after a nuclear explosion. It’s up to a team of teens plucked from imminent death across time to stop the altering of reality—the real reality—and put time back on track. This is an interesting premise populated by engaging, well-developed characters, including an Irish porter saved from drowning on the Titanic, a computer hacker rescued from a fatal plane bombing and a girl from Dubai snatched from a house burning in the future—not to mention the bionic robot named Bob. While the ending brings closure, there are still plenty of opportunities for a sequel, possibly multiples, to follow. (Science fiction. 12 & up)
