Calli Munro, American, soon-to-be economics professor, and single by choice, arrives in Vistaria during La Fiesta de la Luna, a combination of Mardi Gras and Carnival. Calli's there to keep her sex-kitten cousin, Minnie, out of trouble. When she meets Nicolás Escobedo, the powerful bastard half-brother of Vistaria's president, she realizes she is the one in trouble.

Their attraction is instant, powerful and mutual, but to give in to it will open the floodgates of bloody revolution in Vistaria. Not even the mysterious man known only as The Red Leopard can stop it.
