This is How You Lose Her by Junot Díaz

On a beach in the Dominican Republic, a doomed relationship flounders. In the heat of a hospital laundry room in New Jersey, a woman does her lover?s washing and thinks about his wife. In Boston, a man buys his love child, his only son, a first baseball bat and glove. At the heart of these stories is the irrepressible, irresistible Yunior, a young hardhead whose longing for love is equaled only by his recklessness--and by the extraordinary women he loves and loses: artistic Alma; the aging Miss Lora; Magdalena, who thinks all Dominican men are cheaters; and the love of his life, whose heartbreak ultimately becomes his own.
