The Lemonade War by Jacqueline Davies (Paperback)

The first book in Jacqueline Davies's popular Lemonade War series is a funny and relatable story of sibling rivalry. Evan and his younger sister Jessie usually get along, but when they learn they will be in the same class next year, tension boils over into a competition.

Each sets up a lemonade stand to see who can earn the most money before the end of summer vacation, and the contest soon becomes a battle of strategy, pride and hurt feelings. Packed with real-world math and business ideas, this paperback is a favorite in classrooms and with young readers.
