An adventure back in time to Roman Britain brings mortal danger for Topher and his special cat Ka. Can they get back to their own time?
Ka, the time-travelling cat, has vanished again, leaving Topher a clue in the form of a Roman word on his computer: Ca;;LLevA.
At first Topher isn't worried. Surely she's safe among the cat-loving Romans? But when he follows her to Roman Britain, they're both soon swept up in a conflict. As oppressed Britons fight the Romans, Topher faces a desperate choice - to help his British brother or his Roman friend?
