In Smile, Raina just wants to be a normal sixth grader. But one night after Girl Scouts she trips and falls, severely injuring her two front teeth. What follows is a long and frustrating journey with on-again, off-again braces, surgery, headgear and even a retainer with fake teeth attached. And on top of all that, there's still more to deal with: a major earthquake, boy confusion and friends who turn out to be not so friendly.In Sisters, Raina can't wait to be a big sister. But once Amara is born, things aren't quite how she expected them to be. Amara is cute, but she's also a cranky, grouchy baby and mostly prefers to play by herself. Their relationship doesn't improve much over the years. But when a baby brother enters the picture and later, when something doesn't seem right between their parents, they realize they must figure out how to get along. They are sisters, after all.
