An extraordinary thriller ... Vachss never flinches from the horror.
Washington Post Book World

This is a story of legacy. It is a story of a father grappling with the question of how to pass on the mission of his lineage to his son. It is the tale of a two generations bound not by blood but by circumstance and choice. It is the story of a man discovering who his son is, and enabling his son to grow into his strengths. It is the story of a bloodline.

In the world of dangerous men, a blood line is a cause passed from generation to generation from master to protégé. But on the path to becoming a master, each protégé must find their own hunting ground...

When a young girl is lured away by an Internet predator, the young protégé of an assassin who never leaves a trace decides to leave his own mark by hunting down sexual predators targeting vulnerable teens who are bullied and feeling unwanted.

As Sonny discovers his own cause—his own reason for existence—and a skill set beyond anything his master taught him, he steps out of the shadows and joins a long blood line of masters seeking justice on behalf of defenseless children.
