One of the most important and blazingly original writers of his generation, George Saunders is an undisputed master of the short story, and "Tenth of December" is his most honest, accessible, and moving collection yet. New York Times review
The Twelve Tribes of Hattie (Oprah's Book Club 2.0) by Ayana Mathis. Not necessarily a happy story but I liked the 12 chapters narrated by different characters and perspectives to complete the whole story.
Growing up in the same 1970's urban planning development in Northwest London, four young people pursue independent and reasonably successful lives until one of them is abruptly drawn out of her isolation by a stranger who is seeking her help.
