"Linden is admirable at explaining complex scientific concepts for the nonspecialist. He focuses most of his attention on the role played by the small portion of our gray matter known as the medial forebrain pleasure circuit and demonstrates how both behavior and chemistry can activate its neurons. He also discusses the somewhat counterintuitive conclusion that addiction is often associated with decreased pleasure. Linden's conversational style, his abundant use of anecdotes, and his successful coupling of wit with insight makes the book a joy to read. Even the footnotes are sprinkled with hidden gems."—Publishers Weekly
