You're in Trouble(2015)
(The fourth book in the Jasper John Dooley series)
A Chapter Book by Caroline Adderson
After soccer practice, Jasper accidentally chooses the wrong drink from the vending machine. It's fizzy and syrupy and tastes so so good, but Jasper knows it's so so Bad. He sneaks some sips on the way home, then hides it in the fridge. That evening, Jasper has so much energy that he can't sleep. The next morning, he feels awful, but for the rest of the week, Jasper can't stop himself from sneaking sips of the Bad drink and doing more and more Bad things. He bends the rules at soccer, gets his best friend in trouble at school and lands himself in a Very Embarrassing situation. Will Jasper's secret drink be discovered? Will he be Bad for the rest of his life?
