I really enjoyed reading this book and it is one of the best mystery books I have read in a long time. I liked the characters Scipio and Prosper. Like how Scipio was secretive and how Prosper was so determined to find his brother. This book kept your interest and made you want to read on. It made you visualise the city of Venice with all the descriptions that the author gave us. I would say this book is for the age range of 10-15.
