"Don't even think about lending this book - you'll never get it back!" A.M. Homes. Cheryl Glickman is a woman in her forties with a system: she only owns what she truly needs (for example, a plate, a fork, a spoon) and maximizes her energy. If you have to read a book, you might as well do it next to the bookshelf and keep your finger in the gap so you can put it back later. Cheryl works for a company that teaches self-defense for fitness purposes. She has been in love with Phillip, who is twenty years older, for years and is convinced that they have actually been a couple for millennia (caveman and cavewoman). When her bosses' daughter moves in with her, her obsession with order is ruthlessly shattered: Clee, 20 years old, is a hoarder and has no manners. But she shows Cheryl a thing or two.
