In Like Life's" eight exquisite stories, Lorrie Moore's characters stumble through their daily existence. These men and women, unsettled and adrift and often frightened, can't quite understand how they arrived at their present situations. Harry has been reworking a play for years in his apartment near Times Square in New York. Jane is biding her time at a cheese shop in a Midwest mall. Dennis, unhappily divorced, buries himself in self-help books about healthful food and healthy relationships. One prefers to speak on the phone rather than face his friends, another lets the answering machine do all the talking. But whether rejected, afraid to commit, bored, disillusioned or just misunderstood, even the most hard-bitten are not without some abiding trust in love.
