Great sequel. It follows the classic Kaiju series formula: first book is monster vs man, second book is monster vs monster vs man. Is that cliché? Yes, but he brings his unique touch to the story. The monsters are very cool and the story is engaging. You really feel for these characters, including the monster, Nemesis. Just remember to read Island 731 before this book. It is necessary and many forget to give it a read. Narrator did a great job. I love Robinson and hope he writes books forever.
