"Want Not," the sophomore effort of Jonathan Miles, author of the much-praised comic rant of a novel "Dear American Airlines," does not disappoint. "Want Not" leaps nimbly from topic to topic, each sentence providing a miniature window into its author's energetic and wide-ranging mind: from freeganism to conspicuous consumption; from Manhattan's Alphabet City to residential New Jersey to the backwoods of Tennessee; and from neighbors with nothing but geographical location in common to sisters who share nothing but blood.
