Tucker Renfro hasn't seen his little sister in seven years, and when she finally comes to visit, he's sure she's made it her mission to drive him crazy--why won't Olivia leave him alone?Tucker Renfro is obsessed with Native American culture, and nothing is more important to him than his tribe--his dad and his best friend, Joe Allen. When Tucker's sister comes to visit, he isn't exactly excited to see her. Tucker hasn't seen his mother or sister since they left his dad seven years ago, so Olivia is a stranger to him. He cannot believe he has to put up with such an annoying little sister, especially one who won't stop talking about their mother, whom Tucker can barely remember. No matter how hard she is trying, and no matter how much his dad likes having her around, Tucker will not allow Olivia to be part of his tribe. But when Olivia tells Tucker that their mom wants to come back so they can live as a family, Tucker can't help but imagine how great it would be to have everyone together again. Maybe, just maybe, Olivia isn't the "worst" sister in the world.
