Ida B. lives a good life. Her parents rescue her from the mean teacher, opting to home-school her instead. The family lives on an expansive farm, with plenty of trees. There is a never ending supply on fun available to Ida B., most of which she manufactures using her brilliant imagination. Then one day everything changes. Mom is diagnosed with cancer and it becomes painfully clear that this one little word seeps into every aspect of Ida B.'s life, altering it in ways she does not like. This book looks at a family crisis through the eyes of an honest and bold fourth grade girl. We see her struggling to deal with a suddenly quiet home, distant parents, re-entering school, and the loss of dear "friends."
