I loved this book a lot but there were points wear I wanted to skip a paragaph or a sentence becuse it made no sense to the story at that moment or at all in the story. But I enjoyed it becuase included the problems of all four children and how they all fitted together to make one big problem: who was the thief of Ostia? When the answer becomes clear it was obvious and you feel like a big idiot for not realizing it earlier. So the clues were there and it was kind of a game and a book at the same time and the author's desciptions were so spot on you really got a movie in your head from reading the book which is veyr enjoyable.
