I’ve always loved dinosaurs and the Jurassic. Hated zombies with a passion but this was a totally different type of zombie book. It took today’s science of drilling into ice and permafrost to search out the history of our world without the regard for what they may turn up. Nobody knows what is waiting for this world in those ice cores from ice that is from millions of years ago. I really hope nobody releases this kind of plague on the world. This book grabbed you from the beginning and didn’t let go until the end. The scariest part of this book is knowing that something like this could really be released on the world.
