The alien invasion, predicted to result in the extinction of mankind, begins.
After the events of the previous book, Arsenal has been tasked by the President with building a new super team to protect Earth.
Many of the problems from the beginning of the series have been solved: The dialogue and internal monologue issues in the first two books in the series seem mostly resolved and any issues I had with the narrator are no longer noticeable. The rate of Arsenal's technological progress seems to have been slowed down to something more typical of a superscientist from the comic books.
There is some significant character development for the protagonist (though this is a short book, so that's inherently limited). And the world-building is also proceeding apace. The plot is a bit scattershot, but it moves well. The lack of focus does limit the impact of the story, though.
The one big problem I have with this book is that the ending is a full-blown cliffhanger. If I hadn't already acquired the next book, I would be angry, but as it is, I'm just annoyed. These books are quite short; there's no reason for them not to tell complete stories.
The book is entertaining enough for what it is, but it's very insubstantial. If you're a comic book fan, this isn't a bad effort, but if you're not, it's unlikely to make you one.
