February, AD 80. An imperial messenger summons Jonathan's father to Rome, where the fever which started in Ostia is now threatening to become a plague. Jonathan and his three friends go, too, and need to use all their skills to solve a dangerous mystery for the Emperor Titus. Since the first title, THE THIEVES OF OSTIA, was published in September 2001, the series has got off to an amazing start. The first six titles have already been sold in ten languages and the author has had a huge response from children at her many speaking engagements and through her Roman Mysteries website.
