I've always been a fan of Lauren Oliver's books whether they be contemporary or dystopian. However, Hana really let me down. I was expecting a lot more from this novella and in the end, I just didn't get what I expected.Hana really impressed me in Delirium. She wasn't the typical best friend character who ended up being a total backstabber. She was actually a good friend to Lena and while I didn't love her at first, I did by the end of the book. However, she really let me down in Hana. She was immature and really only ever thought about herself. All she cared about was boys and she dreaded the cure and she was positive that Lena could never understand what she was going through. She didn't appear to be a good friend to Lena at all in this novella. I was hoping for an expansion of their relationship but that's not what I got at all.The story didn't really go anywhere. I read Hana thinking that it would help me understand things in Requiem but now that I've read it and have started Requiem, I see no reason for reading Hana. Sure if you want more stories set in the world of the Delirium trilogy, check this one out, but don't expect much from it. Overall, Hana really didn't go anywhere and it didn't contain any information that I felt was necessary to the story in the rest of the books. Like I said, if you want more set in the world of the Delirium trilogy, check this one out but otherwise just pass on this one.
