The Sadist by Jordan Silver

Nico Rosetti is back on Amreican soil after years in Central America. Sent there by his dad as a young man of twenty-two to get his act together after a political scandal involving a high ranking politician’s wife, he’s now a man of means and a tawdry affair is the least of his sins, and they’re about to get worse. The man he holds responisble for his dad’s death refuse to play by Nico’s rules, which are pretty simple. An eye for an eye. His dad was the only family he had left, so to even the playing field, he takes the daughter of his enemy.
