The fire is mine. I am Daenerys Stormborn, daughter of dragons, bride of dragons, mother of dragons, don't you see? (73 Daenerys 10.54)
A lot of kids in this novel experience a coming of age: Bran becomes more thoughtful, Robb partly transforms into a lord, and so on. But Daenerys undergoes a complete transformation from little sister who gets beat up to widowed khaleesi who sacrifices a woman for her dragons. Wow. And what is new Daenerys like? You'll have to read the next book to find out.
