46 parts Complete Harry Styles, at just 16 years old, is the deadliest hitman in the world. Since his childhood, he has been trained to show no emotions and eliminate his targets without hesitation. When he's assigned to kill CIA agent Mark Tomlinson, the plan is clear: He must get close to Mark's son, Louis, by enrolling as a new student at his high school and using him to get to Mark.
But what Harry doesn't expect is the inexplicable attraction he feels toward Louis. As he focuses on his mission, he begins to feel something he hasn't felt in years - something human, something he can't suppress. Louis, innocent and kind, stirs feelings in him that slowly pull him away from his dark past. But Harry knows he has no time to waste - because his emotions could ultimately cost him not only his mission but his life.
