Mount Misery By Samuel Shem

A brilliant novel of doctors and patients in a psychiatric hospital. Mount Misery is a prestigious facility set in the rolling green hills of New England, its country club atmosphere maintained by generous corporate contributions. Dr. Roy Basch is lucky enough to train there *only to discover doctors caught up in the circus of competing psychiatric theories, and patients who are often there for one main they've got good insurance.
