This middle-grade realistic fiction series follows a brother and sister whose competitive natures and very different strengths — he is socially gifted, she is academically gifted — repeatedly bring them into conflict, beginning with a summer lemonade stand competition. The series incorporates math and economics concepts into its plots and is known for its warmhearted portrayal of sibling rivalry and the complementary nature of different kinds of intelligence.
Fourth-grader Evan and his younger sister Jessie, who is skipping into his grade, have a falling out and declare a lemonade war to see who can make the most money by the end of summer, learning lessons about business, fairness, and sibling love. A smart, funny novel that weaves math concepts into an emotional story.
When Evan's hard-earned lemonade money is stolen and a classmate is accused, Jessie organizes a classroom trial to determine guilt, raising questions about justice, fairness, and truth. A thoughtful sequel that explores legal and ethical concepts accessibly.
