Hana, if you remember, is even more of a rebel spirit than Lena, at first anyway, she is the one who takes Lena to her first underground party. Hana is the one who has a secret and forbidden map of the world before, which includes places like France and China. She likes to think about going there and she talks about them, which freaks Lena out because, well the Regulators REALLY wouldn't like that!
I enjoyed this little book so much, that I'd love find out what happens to Hana, so maybe there will be a 2.5 before we get to the last in the Delirium trilogy! At least I can hope!
