What Light | Jay Asher

Sierra's family runs a Christmas tree farm in Oregon - it's an idyllic place for a girl to grow up, except that every year they have to pack up and move to California to set up their Christmas tree lot for the season. So Sierra lives two lives: her life in Oregon and her life at Christmas. And leaving one always means missing the other. Until this particular Christmas, when Sierra meets Caleb, and one life begins to eclipse the other. . .
