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 shoeânothing more than a gumball trinketâleft behind by her father. For Mattie, it becomes a talismanâa 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.
