Second time reading:
I still love the hell out of Kenji, it's so nice to finally read his novella again. Also, these novellas add so much to the reading of the full novels, I highly recommend reading them in order! Not only do they allow us to get to know some of the side characters a lot better, but they also give us important insight into things that the main characters will come to realize later in the story. It is a lot of fun to read the following novels knowing more than the main characters and just waiting in anticipation for them to learn it!

First time reading:
This just in: I would die for Kenji. I love these novellas, I feel like they add a lot to the story. In this one we got to see a bit more of some of the "background character" of Restore Me (book 4) and I loved it!
