A grand first novel by Irish writer Keyes is a hilarious treatise on love's roller coaster. Both elated and exhausted after giving birth to a daughter, the 29-year-old Claire is shocked senseless when her husband James comes to the London hospital not to celebrate, but instead to break the news that he's leaving her for their dowdy downstairs neighbor. The stunned Claire, with new baby in tow, and feeling as big as a summer melon, hightails it back to her family in Dublin to sort out her life. Wandering around her childhood home in her mother's old nightgowns, a vodka bottle in one hand and the bawling Kate in the other, Claire tries to banish images of the frolicking James and his ""other woman."" Her two younger sisters prove to be a comfort--sweet Anna, a hippie drug-dealer, loans Claire money for booze, and haughty Helen deigns to buy it for her. And drunken anguish does have its rewards, for in no time Claire sheds her extra weight, thanks to a steady liquid diet and nights spent on the family rowing machine fantasizing James's ruin. But it is only when Gorgeous Adam appears on the scene that Claire begins to recover a sense of purpose. A college friend of Helen's, Adam exemplifies perfect manhood--and helpfully takes a liking to her, too. But just as things begin crackling between them, James shows up, oh-so-generously ready to forgive Claire for driving him into the arms of the other woman. Torn between the comforts of her former life in London and a new, heartening sense of self-worth and self-sufficiency--not to mention the Gorgeous Adam--Claire finds herself hard put to make a decision. A candid, irresistibly funny debut and perfect summertime read.
