EDIT: After sitting on this for a bit, I've decided to lower this to a 3 star. This story was still entertaining for start to finish, but I just found that as time went, this left no real impact on me. After reading some amazing books this month, full of worlds and characters I still think about, I realized I forgot I even read this... It's unfortunately just not that memorable for me. I do still plan to continue the series though.

For the first 3/4 of this book, I thought this was just OK. It was a unique, good story, but I wasn't in love. The format is really cool and works for the story, but I found it difficult to keep track of side characters or really connect/care about them. Which definitely detracted from some the "hard hitting" moments. Because I didn't care/remember the characters, their deaths weren't shocking or heartbreaking.
But I did like the final twist
