Isla Lacra Scar Island by John Boyd

Denver Noles is a Navy SEAL and Medal of Honor winner who inherits half an island in the Florida Keys after the death of his uncle Harry. Deciding to leave the Navy and change his lifestyle he converts his uncle’s house into a bar and recruits a couple of other SEALS to run the bar, marina and boat yard and for five years they do just that, until an employee asks for his help. Her only daughter was kidnapped by Mexico’s largest cartel. Denver and his buddies head to Mexico to find the girl but get caught up in a conspiracy that puts them in a struggle for their lives between Mexico’s two largest cartels. Their only way out is to go on the offensive to save the girl and her family and themselves. Their hunt takes them to the coast near Cancun and eventually to a daring rescue in the Caribbean.
