Castle In The Sky (Studio Ghibli Library #01)

"Laputa -- Castle in the Sky" ("Tenkû no shiro Rapyuta") is the story of Sheeta, a young girl who wears a mysterious blue crystal around her neck that allows her to defy gravity, and Pazu, a young orphan and apprentice miner who is pretty inventive. They meet when pirates after a treasure and government secret agents hungry for power start chasing Sheeta and Pazu saves her when she falls out of an airship (he catches her when she floats down out of the sky). Muska has been assigned by the Special Agency to obtain the levitation stone while Dola is the captain of the pirate's airship.
