Fifth grader Chloe Silver is good at looking on the bright side. But staying positive has been difficult since her parents divorced and she had to start at a new school. When Chloe is given the chance to try out for the exclusive It Girls club, things are finally looking up again.
Then Chloe is assigned a science project with offbeat Lucy Tanaka and brainy Theo Barnes. Together they create an experiment that tests how people react to different acts of kindness, officially forming the Kindness Club. Lucy and Theo are fun to be around, and their new club means a lot to Chloe. But the It Girls don’t want to share Chloe with anyone else. How can Chloe be kind to all of her friends, and still stay true to herself?
