Requiem - Lauren Oliver

So this book didn't really excite me the way the first too did. I LOVED the first two! I'm not sure why she wrote it in duel perspective for the final book but I actually liked seeing Hana's perspective. At some points I enjoyed it more than Lena's. Lena annoyed me during this book for some reason. Now for the ending. I'm not sure what to think. It really didn't complete itself. It left it open to interpretation so it could go any way. What really happens? I guess it's whatever we want to happen. There really should have been an epilogue to wrap up the entire story in my opinion. But I didn't write it so...oh well.
