But instead of flying into the clouds and back down, she lands in another world, something like her own, but both kinder and somehow much more terrifying. She's not sure if she can ever leave this nearly parallel world and return to her own. And if she did, she isn't sure she'll be able to bring back with her the sense of warmth and love she has grown to cherish. Amazingly, she does both.
