After Killers of the Flower Moon
Empire of Pain by Patrick Radden Keefe
If Grann's excavation of systematic murder for oil wealth left you furious at America's sanitized history, Keefe's dissection of the Sackler dynasty delivers that same cold dread—three generations weaponizing medicine to build a pharmaceutical empire while addiction ravaged communities. It's the Osage murders in a boardroom, with the same meticulous research turning corporate documents into devastating evidence.
