Ten-year-old Dottie Bing is a problem-solver and question-asker who is never more gleeful than when she’s encountering a new dilemma - whether it’s her own, or someone else’s. But when her Grandpa Walter comes to stay (and stay and stay!) he brings the biggest question that Dottie has ever encountered: How do you heal a broken heart? You see, Grandpa Walter is grieving the loss of his beloved wife, Dottie's Grandma Ima. Even though she knows every solution starts with a question, for the first time in her life, Dottie isn't sure what to ask.
