In the beautiful Indochina 30s where traffic Opium is almost out in the open, a young mischievous and courageous girl is going to foil a plot to tarnish the integrity of his father ...... Quite a story, vivid, vibrant, told with a touch of humor ... A real pleasure for the reader. Yes, the drive because it seems that the target audience is primarily young girls of fifteen years, the fact remains that this exotic and romantic investigation may as well appeal to a wider audience , without age limit .... A book not at all colonial connotation, but it is quite surprising to find such a large number of religious references.
