El imperio del Cronarca (Los Héroes del Tiempo 3)

When Pablo and Daniela finally return to the present, they discover that nothing adds up: the streets are different, Roman symbols are everywhere… and a classmate who never existed has appeared. The tremors shaking the city confirm it: someone has changed history. The name hidden in the cracks of time is Kairos, a Chronomancer capable of rewriting the past and ruling the present. He now controls a Roman Empire that never fell, heavily armed troops, and an army of Trackers ready to eliminate any enemy. To redirect the course of history, Daniela and Pablo must travel to distant eras, survive cities dominated by colossal temples, combat arenas, and ghosts that seem to guide them… or deceive them. Stopping Kairos will be a race against time. Will the Heroes of Time manage to change their own destiny?
