3.5/4 stars.

I enjoyed the premise behind this story, but found the characters lacking a little. I wanted more from them and wanted to feel more for them and the trials they faced. Sadly, I just didn't find myself invested. That in no way implies that this book isn't good, it is, and it is well written. I however just didn't resonate with the characters as deeply as I have in similar stories.

The ending however is quite good and leaves it poised for the sequel.
