Cynthia Jane is pretty proud of being Lucy's older sister. They may get dressed the same by their Mom, and Lucy may be bright, but Cynthia Jane is the eldest, has more friends, and is a writer to boot! That all changes when Lucy gets promoted into Cynthia's math class and starts to make friends there.
A charming short book about sibling rivalry for middle readers. Nothing deep or earth shattering is learned and the 3rd party narrative style will leave you a bit distanced from the characters and the story, but it is an enjoyable read.
