They killed the perfect missionary. His brother is the perfect mercenary. Now he’s wearing the name tag to hunt them down.

When Rockwell and his parents are brutally executed in a Rio favela , his brother Angelo—a lethal ex-special forces contractor—descends into the city's corrupt heart to find the men responsible.   

But the official report is a lie. The killers are being protected. To get to the truth, Angelo must do the one thing he swore he'd never do: go back to the pious world he left behind.

He goes undercover as "Elder Rockwell", a wolf hiding in the one flock that won't see him coming. Now, a man of violence must walk in his brother's footsteps, navigating a world of naive companions  and strict rules, all while hunting a ruthless favela boss.   

The deeper he digs, the more he realizes the true evil isn't on the streets. It's in the penthouse, festering in a dark conspiracy of religious zealots, unholy experiments , and a "harvest"  worth killing for.
