An action, adventure story awesomely told. As with Caroline Lawrence's other stories, I couldn't put the book down, and kept reading until the end. I like this book so much because of the way the story is told. I felt as if I was a part of the excitement. Set in ancient Rome, four children must discover who has been kidnapping children after the eruption of Mt. Vesuvius. Suddenly, they find themselves in a world of slavery, misery, and hardship after being kidnapped by the slavers themselves! Could the mastermind of the whole thing be the Patron, an extremely powerful person who is the Emperor Titus` friend? Or is the real criminal a different ill wisher? Definitely a book action lovers must read!
