In Fresh Air Fiend, Theroux's pen serves him well with astute, lively pieces that stray far beyond simple "travel essays" and reveal his self-inflicted lifestyle of compulsive travel, writing, and alienation. In this collection--containing mostly previously published magazine pieces written over the past 15 years--there's a strong autobiographical streak, as well as historical perspectives and a sardonic view on aging. "One of the more bewildering aspects of growing older," he writes in "'Memory and Creation,'" "is that people constantly remind you of things that never happened."
