Plot

Soon after the start of the 21st century, during construction on the London Underground, workers penetrate a cave and a huge dragon emerges from hibernation, incinerating the workers with its breath. The only survivor is a boy, Quinn Abercromby, whose mother, Karen —the project engineer—is crushed to death protecting him. The dragon flies out of the Underground, and soon more dragons appear. Years later, Quinn, now an adult, records the events that transpired after the first dragon sighting. Scientists discovered that dragons were the species responsible for the extinction of the dinosaurs and most plant life on the planet when they razed it with fire; the ash from this event caused the first Ice age before the dragons disappeared, presumably in a cycle of hibernation. Once re-emerged, the population surged to several million, prompting most militaries to use increasingly devastating weapons, finally leading to targeting the largest population areas with nuclear weapons in 2010; however, this only hastened the destruction, and by 2020, humans are nearly extinct. The dragons, now starving as well, are dying off and increasingly aggressive in search of food.
