I became intrigued with Elmore Leonard's books after watching "Justified", especially his interview in one of the bonus features. This is the first book I have read. It has a very interesting style, almost a shorthand that allows you to fill the gaps.
This story begins with 2 American cowboys contracted to deliver a shipment of horses (and some other stuff), who arrive in Cuba 3 days after the Maine is blown up in Havana's harbor. It's filled with a multitude of disreputable characters who each seem to have their own code of honor. Leonard switches the attention from character to the next making sharp plot twists.
My overall impression is of a mostly complaisant society corrupted by colonialism.
