Deep Sky, by Patrick Lee ($7.99)

I admit to being hampered by not having read the first two books in Patrick Lee's "Breach" trilogy, The Breach and Ghost Country, but Lee explains enough that I wasn't asea when I started Deep Sky.

A breach in time and space has been opened, and a secret, independent organization, Tangent, monitors it. Odd technology erupts from the wormhole every once in a while, technology pretty far removed from what scientists on Earth are capable of producing. There's a suit that can make a person invisible, a tiny cube that allows the user to journey back in time to a memory and to live during that memory's moment, and doodads like that. That's enough to give the idea that this book may not be a typical political thriller, although it starts with the President of the United States being killed by a missile while giving a televised speech.

Travis Chase and Paige Campbell are two members of Tangent, and they soon figure out that whoever killed the president is gunning for Tangent next.

The rest of the book is a cat-and-mouse game between Chase, Campbell, their allies and the shadowy bad guys. The breach is at the heart of the matter, however, so that the ultimate goal is to find out what it is. Why is Tangent protecting it and why do the bad guys want to gain control over it?

Deep Sky was exciting and peculiar. It's plot-driven and doesn't pretend to be anything else, except at the end. Enjoy it for what it is: political thriller and sci-fi in one neat package.
