Chloe Silver has always been good at looking on the bright side. Even though her parents got divorced and she's moved to a new town, she knows that she will make great friends at her new school. So when she is assigned a science project with offbeat Lucy Tanaka and nerdy Theo Barnes, they have fun creating an experiment that tests out the laws of science through different acts of kindness . . . officially forming The Kindness Club.

But when she is also asked join the cool girls' exclusive It Girls club, Chloe feels completely torn between the It Girls and The Kindness Club. Faced with the possibility of upsetting all her new friends, Chloe's capacity for kindness is put to the test. Sometimes mistakes yield the best discoveries, and there is one hypothesis that can always be proven correct: Kindness is the coolest.
