While this is the first thriller I've read by Nick Thacker, I have read a lot of Lee Childs and James Rollins. The Amazon Code is a fast-paced, page turner. I've read a lot of Nick's Sci-Fi and they were great!! This thriller has them beat. It keeps you on your toes, as a group of scientists go through the Amazon searching for a lost city, while being chased by killers who are after the same thing. You will have a hard time putting it down. Nick really brings the Amazon to life. So much so that you will think you are really there. There are so many twists and turns that surprise you and only add to the excitement. Nick is definitely making a name for himself in this genre. I will be going back and reading The Golden Crystal, although it isn't necessary to read to thoroughly enjoy The Amazon Code. I can't wait for the next one. You won't be disappointed if you like thrillers. The Amazon Code is definitely worth your time and money. Don't miss it.
