As the final days of summer heat up, so does a sibling showdown over a high-stakes lemonade stand business. Jessie and Evan Treski compete to see who will make $100 first off of their respective lemonade stands. Full of surprisingly accessible and savvy marketing tips for running a stand (or making money at any business) and with clever mathematical visuals woven in, this sensitively characterized novel subtly explores how war can escalate beyond anyone's intent.
It is the dog days of summer, and siblings Jessie and Evan are divided about how to spend their last few days before school starts. Sometimes, his younger sister Jessie rubs Evan the wrong way, especially now that she is skipping a grade and will be in the same class as him. The two could not be more different. Jessie is great at school (especially math), but she has a hard time understanding people and sometimes makes poor social choices. Evan, on the other hand, is a master of "sweet talk" but cannot do a complicated math problem to save his life. So when the two siblings, in the wake of a hurtful argument, open rival lemonade stands to settle a bet about who can make more money, their different skills come into play in a big way. Jessie and Evan's relationship is portrayed in a humorous but realistic way, fights and all. The novel effectively combines math (especially money), economics and marketing to make a suspenseful, subtly educational plot that goes down as easily as a cool glass of lemonade in August.
