"The seven kingdoms of Dreamside need a legendary hero. Instead, they'll have to settle for Cucumber, a nerdy magician who just wants to go to school. As destiny would have it, he and his way more heroic sister, Almond, must now seek the Dream Sword, the only weapon powerful enough to defeat Queen Cordelia's Nightmare Knight. Can these bunny siblings save the world in its darkest hour...? Sure, why not?"-- Back cover of volume 1.
