It's summertime, and 13-year-old Nina Ross is feeling kind of lost. Her beloved grandma died last year; her parents work all the time; her brother's busy; and her best friend is into clothes, makeup, and boys. While Nina doesn't know what "her thing" is yet, it's definitely not shopping and makeup. And it's not boys, either. Though...has Eli, the boy next door, always been so cute? This summer, Nina decides to change things. She hatches a plan. There are 65 days of summer. Every day, she'll anonymously do one small but remarkable good thing for someone in her neighborhood and find out: Does doing good actually make a difference? Along the way, she discovers that her neighborhood, and her family, are full of surprises and secrets. In this bighearted, sweetly romantic novel, things may not turn out exactly as Nina expects. They might be better.
