Summary: Siblings--Evan, a 4th grader, and Jessie, his younger sister who is skipping ahead to his grade--compete to see who can generate the most money selling lemonade before the end of summer break. Evan struggles with feeling inferior to Jessie who is very smart in math. She, on the other hand, finds it hard to understand people (her symptoms read like a child with Asperger's, perhaps?), and wishes that her brother would help her navigate the scary world of entering 4th grade.Although the math and business content is phenomenal, perhaps more importantly, the story illuminates the very complex feelings of two siblings who deeply love one another, all while grappling with the realities of their own strengths and weaknesses. This would be a great book to read aloud and discuss.
Recommended age: 9 & up
