Thirteen-year-old Queen Nora of Weeville must fight to save her kingdom when a stranger named Ruby lays claim to the throne. Nora seeks help from a wise fairy in the Forsaken Forest. The fairy will help Nora, but in return, she must promise to help find the fairy's sister, who has been kidnapped and is next in line to rule the fairies. Nora uses the fairy's plan to keep her kingdom, but when it ultimately fails, Ruby takes over the throne.

Nora and her sister, Princess Daphne, are banished to the dark forest and make their home in an abandoned shack. But life in the forest is not without trolls, bats, giant falcons, and other strange things.

Nora remembers her late mother's diary, which may hold the answers she needs to regain her kingdom, but she will have to break into the castle to find it.

Once inside the castle, Nora realizes that under Ruby's cruel reign, Weeville is not the happy village it once was. With the diary in hand, Nora and Daphne confront Ruby, but things take an unexpected turn. In her quest to prove Ruby is not the true queen, Nora also finds something unexpected.
