This Book Will Save Your Life by A. M. Homes

'I think this brave story of a lost man's reconnection with the world could become a generational touchstone, like Catch-22 or The Catcher in the Rye ... And hey, maybe it will save somebody's life'
STEPHEN KING

Trading stocks and shares out of his beautiful LA home, Richard Novak sees no one except his trainer, housekeeper and nutritionist, who delivers regular supplies of macrobiotic, low carb food. He is so out of touch with his feelings that his life has slowed almost to a standstill. Following an attack of inexplicable and excruciating pain that lands him in the emergency room, Richard befriends Anhil, a doughnut shop owner. His Solitary routine broken, and his diet sabotaged by sugary baked goods, Richard's dramatic emotional thaw begins ...

A sharp and wildly entertaining novel about new beginnings, transformation and the weirdness of LA, This Book Will Save Your Life reveals what can happen if you are willing to open up the world around you.
