For generations, the kingdom of Arcadia has been ruled by the Floyd family, each first born son taking the throne at the age of 21. Princess Izalie has spent her whole life training by the side of her brother, Prince Isaiah, but when it is time for Isaiah's coronation, a robbery at the palace sends the kingdom into riots. In the mad panic, Izalie discovers the disappearance of her antique mirror. Upon finding it, Izalie discovers a portal to the land of Ezlandria, the fairy kingdom. At her arrival, Izalie not only looses her mirror, again, but also learns of the seemingly 'perfect' kingdom's turmoil; a battle between the Dark Knights and the Fay court is brewing and only she can stop it, along with the ruling King, 17 year old Daniel Aarons. Faced with the prospects of being trapped in Ezlandria indefinitely, a growing love for Daniel, and a coming war, Izalie must make decisions that will save a kingdom... or destroy it.
