In Magikos, life is dictated by the Book of Fate, which predicts everything. Well, everything important, at least, like the birth of a royal Chosen One who will save the land. And, sure enough, Prince Marco is born on the appointed hour.and is soon followed by a twin sister, who did not merit a mention in the Book of Fate. Now thirteen, Prince Marco is hailed as the land's salvation, while it's clear to all that Princess Marabel is nobody special. If she tried to perform any great feats of bravery, she would most likely fall flat on her face. She won't be beloved by the people, travelling musicians won't regale crowds with the Ballad of Marabel the Great, and she certainly won't be able to unite a fractured kingdom. But when Marco is kidnapped by an evil queen, Marabel is the first to run to the rescue.

Outside of the castle walls for the first time, accompanied only by her best friend and one very smug unicorn, Marabel must forge her own path on a daring mission that sees the crew of rescuers facing off against fairies, trolls, giants, and even a dragon. Marabel will have to find a way to surmount all the obstacles in her path and defy the Book of Fate, or risk losing her brother--and her kingdom--forever.
