Recommended by IndieBound.org, The Unnamed by Joshua Ferris.
Tim Farnsworth is a handsome, healthy man, aging with the grace of a matinee idol. His wife Jane still loves him, and for all its quiet trials, their marriage is still stronger than most. Despite long hours at the office, he remains passionate about his work, and his partnership at a prestigious Manhattan law firm means that the work he does is important. And, even as his daughter Becka retreats behind her guitar, her dreadlocks and her puppy fat, he offers her every one of a father's honest lies about her being the most beautiful girl in the world.
He loves his wife, his family, his work, his home. He loves his kitchen. And then one day he stands up and walks out. And keeps walking.
