Time travel can be unpredictable.
In this sequel, a TimeRiders team intends to travel back several decades to prevent an event that would throw everyone into the “wrong” future. But things really go awry when Maddy mistakenly opens the wrong window, throwing them (along with everyone around them) back several millennia. It’s up to Liam and his robotic support unit Becks to protect the group from carnivorous and all-too-crafty dinosaurs, while devising a way to send a message back to the future. Meanwhile, locked in New York City in a never-ending loop of September 10-11, 2001, Maddy and Sal work feverishly to conserve enough energy to open another window for a rescue, but they face the challenge of a secret government agency that waits for the day that Liam’s message, discovered in the 1940s, can be delivered. The agency wants the secret of time travel for itself, spelling disaster for the future. But what could be worse than the survival of a previously unknown breed of dinosaur that has actually learned how to adapt, just by watching Liam and Becks in the past? It’s another wild ride through time, with the team always aware that changing one minor event can have devastating consequences to the future. Scarrow blends adventure with history in a way that goes down painlessly.
