''For a full hour, he poured lemonade. The world is a thirsty place, he thought as he nearly emptied his fourth pitcher of the day.'' And I am the Lemonade King. Fourth-grader Evan Treski is people-smart. He's good at talking with people, even grownups. His younger sister, Jessie, on the other hand, is math-smart, but not especially good with people. So when the siblings' lemonade stand war begins, there really is no telling who will win--or even if their fight will ever end. Brimming with savvy marketing tips for making money at any business, definitions of business terms, charts, diagrams, and even math problems, this fresh, funny, emotionally charged novel subtly explores how arguments can escalate beyond anyone's intent.Awards: 2009 Rhode Island Children's Book Award, 2007 New York Public Library 100 Titles for Reading and Sharing, North Carolina Children's Book Award 2011, 2011 Nutmeg Award (Connecticut)Don't miss the website www.lemonadewar.com or the sequel ''The Lemonade Crime'' (2011).
