Beyond the end of the world

"Above, in the cloudlands, Nimh has no memory of her past, only an aching, undying certainty that she has left something--someone--behind. Below, on the surface, North looks to the sky, desperate to join the person he loves and return to his world. In their desperation to reunite and save their people, Nimh and North face one ultimate question: can they defy their love and their destiny to save their homes? Or will the spark between them ignite their worlds, and consume them all together?"--Provided by publisher.
