SMILE. Raina can't wait to be a big sister, but once Amara is born she realizes things won't be quite what she had expected...or hoped. Despite Amara's cuteness, she is 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 their parents' relationship starts to struggle, they realize they must figure out how to get along. They are sisters, after all.
