The Killing Jar (The Extraction Files #1) by R.S. McCoy

The Killing Jar - R.S. McCoy
Now, before I start, let me say that R.S. McCoy is an author that I have long admired, for the twists and turns she can put on her books. So I was expecting something 'different' when I started reading The Killing Jar, but not what I got! 
This book is told from multiple points of view which, although slightly confusing to begin with, quickly becomes necessary as you learn about the characters, their world, their situations and what lies ahead of them. 
With an intricate and in-depth story, fascinating characters, backstories and plot twists, this was a thoroughly enjoyable Sci-Fi. This is a slow-burner of a book, don't expect to be swept away from the very beginning. However, if you stay with it, you will be pulled into this world, with it's class system and rules. By the time you are partway through, you will be completely bound to this book, needing to know what happens next. 
With no editing or grammatical errors that jumped out at me, I would have no hesitation in recommending this.
