This book surprised me. First, there were the original Dell/Gold Key comics from the 50's-70's. Then, Valiant resurrected it in the 90's. A Turok animated movie was released half a decade ago and there was an IDW Jim Shooter update a few years ago. This version completely different--and it's a great one.
Turok is presented much younger than in the original comic version. He's a loner by choice as the nearby tribe views him as deserving punishment because his parents belonged to an enemy tribe. He's taunted by a young man his own age, Andar, and two of Andar's friends. They're conflict is interrupted by the arrival of some very strange and violent creatures--dinosaurs. And they were brought here by foreign invaders who have transported them--living weapons--to this new land. You see, they are Crusaders from England and this is Manhattan, 1200 A.D. Turok and Andar become allies--and have to figure out what to do about this invading force. And it has to do with these new creatures, the dinosaurs.
I loved this book because it not only exceeded my expectations but went in an entirely different direction than what I thought it would. There are plenty of prehistoric creatures but there's no "Hidden Valley" Turok and Andar are trying to escape from. They are simply trying to protect their home. The dinosaurs all come from the Old World and in their own land Mammoths still roam the countryside. This is a very intriguing alternate-reality Earth. Highly recommended.
