I took off a star mainly because the first third of the book was a bit disjointed and ran like a misfiring roadster. It was a bit disconcerting to say the least to be following several story lines only to find out that one of them, for no apparent reason, took place 8 years before the other action in the book. The prologue, although amusing, really didn't relate to the story. It was like a really good movie that suffered from bad editing. It leveled off after that and was smooth and fast to the conclusion, although I could have used a bit more back-story as to how and why anyone wanted to create a large breed of vicious ants in the first place. As with the other books by Strand that I have read, the writing is smooth, the dialogue witty, and the story was compelling--exciting even. I will also say that as soon as I finished this I bought two more Jeff Strand books on Kindle. He is one of those authors that I will read absolutely everything he writes.
