The 4th book in the series and it keeps being engaging. It's all a madcap ride down a path where you have no control. Jack West just doesn't know what happening and how he come to be fighting for not only his life but also that of his family and friends. None of what is happening makes sense to him.

But it's all part of a plot to rule the world, while at the same time saving it from cataclysmic future.

An exciting read. Now the long wait begins for the next in the series.
