Black Machetesaf R. K. Howard

Benjamin Wilder grew up with sparse shelter, infested provisions, and constant abuse dealt to him by his stepfather: Jessup — a.k.a. the Rabid Dog. Without a sober mother to defend him from the Rabid Dog’s wrath, Ben finds reprieve and adventure in a club of misfit boys called the Black Machetes. But the world as Ben knows it comes to an end when he witnesses an act so psychologically appalling that it forces him to run for his life. 
"Black Machetes" is a powerful page-turning thriller that all readers agree is both shocking and endearing, written in gritty-cinematic tones that paint a painfully intimate portrait of life framed by abuse, tragedy, and inhibited love.
