Carry the one / Carol Anshaw.

Enhanced descriptions from Syndetics:

This stunning, break-out achievement has already been hailed by Emma Donoghue, bestselling author of Room , for presenting "passion and addiction, guilt and damage, all the beautiful mess of family life. Carry the One will lift readers off their feet and bear them along on its eloquent tide."

C arry the One begins in the hours following Carmen's wedding reception, when a car filled with stoned, drunk, and sleepy guests accidentally hits and kills a girl on a dark country road. For the next twenty-five years, those involved, including Carmen and her brother and sister, craft their lives in response to this single tragic moment. As one character says, "When you add us up, you always have to carry the one." Through friendships and love affairs; marriage and divorce; parenthood, holidays, and the modest calamities and triumphs of ordinary days, Carry the One shows how one life affects another and how those who thrive and those who self-destruct are closer to each other than we'd expect. As they seek redemption through addiction, social justice, and art, Anshaw's characters reflect our deepest pain and longings, our joys, and our transcendent moments of understanding. This wise, wry, and erotically charged novel derives its power and appeal from the author's exquisite use of language; her sympathy for her recognizable, very flawed characters; and her persuasive belief in the transforming forces of time and love.
