Phytosphere by Scott Mackay was one of those books that I had on my shelves but had no real idea of how it got there or where I'd found it. I'd never heard of the author. The cover art wasn't very good. When I decided to give it a try, I didn't really expect all that much.
I was wrong. It is absolutely great. Sure, aliens trying to destroy Earth isn't exactly a new theme, but this story is written so well and so realistically that it is nearly impossible to put down. It turned out to be one of my very favorites.
