Mattie Ryder is marvelously neurotic, well-intentioned, funny, religious, sarcastic, tender, angry, and broke. Her life at the moment is a wreck: her marriage has failed, her mother is failing, her house is rotting, her waist is expanding, her children are misbehaving, and she has a crush on a married man. Then she finds a small rubber blue shoe—nothing more than a gumball trinket—left behind by her father. For Mattie, it becomes a talisman—a chance to recognize the past for what it was, to see the future as she always hoped it could be, and to finally understand her family, herself, and the ever-unfolding mystery of her sweet, sad, and sometimes surprising life.
