The Christmas Stradivarius

In New York, the elections are approaching, but the Mayor of the city has a formidable opponent, Keissel.
Keissel ? He is a ruthless and dangerous man, a maniac of firearms, with retrograde ideas and obliges, by his intolerant ideas, the Mayor of New York to do the same.
But bad luck for Keissel ! A young and little teenage girl named Rose, who lives on the street, will shake up these demonic and pernicious ideas; and, in spite of herself, upset the entire destiny of the United States.
