The Lemonade War takes place during the last week of summer vacation when Evan and Jessie decide to set up a lemonade stand to see who can make the most money.

This all-out war between the siblings gives rise to various strategies, betrayals, and sabotage. As the siblings try to outdo one another, they eventually realize the importance of working together and combining their unique strengths.

Book Reviews on Amazon

5 Star Book
My 8 yr old son loved this book. Good first business book for kids. - Gita

An easy, entertaining read!
Just the book I needed when my 9 YO hit a bit of a reading dry spell - she zoomed right through it and couldn’t put it down! It was an easy, engaging and fun read. Involves some sibling rivalry, some early economics, and a lot of humor and charm amongst other things. Would love to get my hands on the whole series! - A. Vargas

Great Book!
My Grandson loved this book. It was funny and he related the situations to some of the situations in his life. I had no trouble getting him to read this book. - Carolyn D.

Five Stars
My grade 3s and 4s love this book! Very entertaining and throws a little math into the fun! - Charlene P.

Exceptional middle grade novel!
I haven't read the entire series, but I'm very impressed with the quality of this first novel in the series. Kudos to the author for presenting a positive view of entrepreneurship, in an age when children are brought up on a diet of movies about the evil developer who wants to build a shopping mall on the wildlife preserve. That alone makes this book a stand out. The author skillfully weaves several sub-plots and themes into the story. When I teach this book, my students learn about "reading between the lines," skilful and well-paced exposition, fresh and imaginative metaphors, as well as neurodivergent children, learning disabilities, conflict resolution and first crushes. Terrific book, highly recommend. - impulsesleuthcat


Overall, The Lemonade War is a fun and engaging book that will appeal to young readers, especially those interested in business and entrepreneurship. With relatable characters and an engaging plot, this book is sure to be a hit with kids, making it a valuable addition to any school or home library.
