In her densest, most ambitious work yet, chick lit specialist Keyes (Sushi for Beginners
) pushes into dark territory, exploring alcoholism, depression and domestic violence with authenticity and even offbeat humor. When Paddy de Courcy, “Ireland's most eligible politician,” announces his engagement, the news breaks hearts all over Dublin. Lola Daly, a celebrity stylist who has been dating him for the past 16 months, is the most heartbroken of all and retreats to County Clare. Meanwhile, Dublin reporter Grace Gildee remembers Paddy from their college years, when he had a chaotic, codependent relationship with her twin sister, Marnie. Grace digs a little, and as the true extent of Paddy's capacity for evil is revealed, Grace moves to stop him—and to finally teach him a lesson. To do so, she must make fragile Marnie revisit the most painful years of her life and engineer Lola's return to Dublin. Dry wit and distinctive narrative voices add levity and balance to a sad set of life circumstances. Pages will fly like wafting hankies toward the stunning, breathless conclusion. (June)
