All her life, Droplet has been the 'good one.' She was always more responsible than her siblings, shy and less willing to disobey their mother. But when she unleashes a magic she doesn't understand, starting a conflict in the kingdom of sea, she feels she has no choice but to run from her mistakes. When she stumbles upon a danger that could end the world as she knows it, she must make a choice: to save herself, or step up and risk everything she loves.
