What’s it about?

The story.

In the historic city of Birchester, built on the ruins of Roman Britain, Sophie and Sienna are exploring the famous sights when a message from an unlikely source hurls them into a terrifying adventure. Hidden beneath the city's crumbling ruins lies a powerful secret, one that can create fortunes and build empires, and Sophie knows they must find it before it is too late. But a dangerous fugitive is on its trail too, and he will stop at nothing to seize the power he craves. The sixth book in A.B. Martin's Sophie Watson series wraps an ancient, buried secret in a fast, deadly chase against a time limit and a ruthless enemy. Told at the series' brisk, filmic pace with short cliffhanger chapters, it suits confident 9-13 readers who like adventure-mysteries with history, jeopardy and high stakes, and reads well aloud to slightly younger listeners who enjoy the thrill.

Fit check

Right for your child?

Where it lands by age

Best fit is confident 9-13s reading independently, drawn by the history-meets-treasure-hunt premise and fast pace. It reads aloud from about 8 for children who like peril, though the jeopardy makes it less of a bedtime pick. Little adult crossover.

Why kids love it

There is a real Indiana-Jones thrill to hunting a power-giving secret buried beneath a city's Roman ruins, especially with a ruthless fugitive racing for it too. The clock is ticking, the danger is closing in, and Sophie and Sienna have to get there first.

  • Adventure and freedom
  • Surviving danger
  • Being a detective
  • Going on a quest
  • Friendship and belonging

Why parents love it

A fast, clean adventure-mystery that layers Roman-Britain history over the series' dependable chase-and-escape thrills, with a race against time and a ruthless enemy but no gratuitous edge. The short cliffhanger chapters keep reluctant readers turning pages.
