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.

Or will the spark between them ignite their worlds, and consume them all together?
