When Arica falls through a crack in her grandmother's kitchen floor, she finds herself in a strange world of fairies, trolls, elves and - best of all - unicorns. But the trolls and their evil master, Raden, take her prisoner, just as they have the unicorns. Fortunately, Arica discovers that she can hear the thoughts of the unicorns, in a way that no one else in this world seems able to. With the help of Wish, a playful young unicorn, Arica sets out to free the captives - and discover the true reason she was brought to this magical land.
