Tillie Amartey is in the north east of England to explore Hadrian’s Wall, and the ancient civilisation that built it – the Romans. 

But when an accident sends Tillie 2000 years back in time, she finds herself much closer to Roman life than she bargained for. 

As Tillie tries to get back to the modern day, she discovers the surprising things Romans brought to Britain, finds out why they were definitely cat people, and learns some Latin insults.
