An account of the inner workings of a pharmaceutical company could have been dull in the hands of another author, but Hughes brings it to life beautifully. He weaves together a vivid cast of characters—doctors, sales reps, and executives—with key commentary illustrating the connections between a relatively small drug company named Insys Therapeutics and the broader opiate epidemic. As compelling as a true crime documentary, the book details Insys’s relentless quest to corner the drug market with its version of fentanyl and chronicles the resulting federal trial.
