Eleven-year-old Perry did not expect anything from a trip to France, but everything changed in an instant. Step onto the ruins of a villa from the time of southern Gaul - and the boy found himself in the fourth century of the Roman Empire! Perry did not know what to do, so he posed as Peregrine and began to get used to the role of a slave. It was even fun to serve Valentia, the daughter of the owner of the villa. But Perry couldn't help feeling that the girl's name was very familiar to him... But from where? They are separated by millennia. The boy needs to decide: to satisfy his curiosity, but stay in Ancient Rome, or rather return home?
