Lord Garrett Embrey is on the run. The Leviacrum Council, the secretive scientific body that holds sway over the Empire, executed his father and uncle and now they want him dead too.
Professor Cecil Reardon is consumed by grief. Since his wife and son died he’s been obsessed with his work, and now he is on the verge of an extraordinary scientific breakthrough: his machine is about to breach time itself, to undo fate’s cruel taking of his loved ones.
But the time jump doesn’t go according to plan, and part of London winds up millions of years in the past. Verity and her crew—Lord Embrey, Professor Reardon and others stranded with them—must pull together to survive in a world ruled by dinosaurs…and to somehow get home.
