First, let me start by saying you do not have to read Converted and Discloser to follow this book, but I recommend it. They are significant lead-ups and give a good introduction as to what's going on. Reading those first will help you ease into this book smoothly.
From the start, you are sucked in. Pesci has done such a fantastic job with his writing that you feel like you are one of the characters. It is almost like you are sitting in the FACT classroom right along with Marcus and his peers.
The writing style makes you think that Douglas Adams, Ernest Cline, and Blake Crouch had some kind of love child, and it's Luciano Pesci. Incredible!
Pay attention because this book is very descriptive, and you can easily get lost.
If you are a sci-fi fan, then this is a must-read. I am looking forward to what comes next.
