Another town. Another school. Another Mclean. Ever since her parents’ bitter divorce, Mclean and her father have been fleeing their unhappy past. And Mclean’s become a pro at reinventing herself with each move. But in Lakeview, Mclean finds herself putting down roots and making friends—in part, thanks to Dave, the most real person Mclean’s ever met. Dave just may be falling in love with her, but can he see the person she really is? Does Mclean herself know?
