Emma-Jean Lazarus is the smartest and strangest girl at William Gladstone Middle School. Her classmates don't understand her, but that's okay because Emma-Jean doesn't quite get them either. But one afternoon, all that changes when she sees Colleen Pomerantz crying in the girl's room. It is through Colleen that Emma-Jean gets a glimpse into what it is really like to be a seventh grader. And what she finds will send her tumbling out of a tree and questioning why she ever got involved in the first place.
