This is the fourth book in Robinson's "NEMESIS" series. Nemesis is a creature that's part of an ancient monster that's been cloned combined with a young girl, Maigo. The result is a rampaging, Godzilla-like Kaiju that's bent on revenge. In the first book it seeked to find the man who killed his own daughter-and it did, with mass destruction of Boston. Then Nemesis became more of an ally, fighting against even worse monsters. By the third book the creature Nemesis and the consciousness of Maigo, the young Japanese girl, become separated, so that Maigo now has her own human form. And Nemesis is controlled by someone else. Involved with all of this is Jon Hudson, who becomes the director of the Department of Homeland Security's Fusion Center-Paranormal. He not only has a connection with Nemesis from the beginning-but adopts Maigo once she separates from the creature. There's also Lilly, a cat-like chimaera introduced in Robinson's ISLAND 731, who is Maigo's friend and co-worker, who also work for the organization. When investigating a clandestine organization in the Arctic, they come across a giant robot-Hyperion, which Maigo is able to take control of, sort of like "Johnny Socko and his Giant Robot". And it turns out that this ancient giant machine was create in order to battle creatures like Nemesis, who were created as planet conquerors by an alien race. Whew.
On one hand some of the loose writing irritates me and I'm ready to toss the book-but obviously I didn't and proceeded to read all four of them, so they did keep my interest. Basically, if you've seen all the Godzilla movies and are looking for something new that has the same "feel", then you'll probably enjoy this series.
