Family, fairness, and...lemonade? This first installment in the award-winning Lemonade War series follows a battling brother-sister duo as they start competing businesses, gather savvy marketing tips, tackle practical math, learn business terms, and dig into a good old sibling rivalry. When Evan Treski finds out that his younger sister is skipping third grade and joining his fourth-grade class, he is not happy. The last thing he wants is Jessie showing him up with her perfect grades, and he definitely doesn't need her help getting his lemonade stand up and running...even if the business side of things has got him confused. Jessie doesn't understand why Evan won't team up with her, but she's got a plan to set up her own lemonade stand to prove her worth. Now if she can just figure out how to attract customers as easily as Evan can, she'll be able to show him what he's missing. Can these siblings do it all on their own, or will they need each other after all? And will their lemonade war ever end? Brimming with ideas for making money at any business, definitions of business terms, charts, diagrams, and even math problems, this fresh, funny, emotionally charged novel explores how arguments can escalate beyond anyone's intent--and the unique rivalry (and partnership) that comes with having siblings.
