If there’s one thing ten-year-old Dottie Bing learned from her grandma Ima, it’s that any problem can be solved if you ask the right question. And because life is full of so many problems, Dottie Bing is already a champion question-asker. But when Ima dies and Dottie’s Grandpa Walter comes to stay (and stay, and stay!) he brings the biggest problem Dottie has ever encountered---a broken heart.

For the first time in her life, Dottie isn’t sure what question to ask. Luckily, there are a lot of other problems (and questions) on her mind: How can someone look happy but feel sad? Can someone who used to annoy you ever become a friend? And the scariest of all: are there any problems the right question can’t solve?
