London, 1835: Young Princess Victoria has vanished from Kensington Palace without a trace. The only man who can help? Rufius Westinghouse, a mysterious watchman for a secret Order of Time Travellers, charged with keeping history on its proper course. As Rufius races to prevent the unraveling of Europe’s royal future, he uncovers a conspiracy far stranger than a mere kidnapping: the Russians have torn open a wormhole to the Cretaceous period and are harvesting dinosaurs. With Europe’s future hanging by a thread, Rufius must rescue the future Queen of England before her disappearance rewrites history forever—and before those dinosaurs can be used for an even more sinister purpose. Time travel has rules. The past has teeth. And saving Victoria might just be the least strange part of Rufius’s day.
