The Martian by Andy Weir

An outstanding science fiction thriller about an astronaut stranded on Mars. It's "near real" sci-fi, in the sense that Weir stays as close to known science and a realistic mission to Mars as possible. One of the best works of fiction I've read in years. Looking forward to the movie.

Faith vs Fact by Jerry Coyne

I've written some posts about this book on my main blog. A great look into the modern scientistic mind.

The New Organon by Francis Bacon

Long intended to read this and finally got around to it.

Skeptics and True Believers by Chet Raymo

Picked this up for a few $$$ at the used book store. Usual stuff about folks who accept science (yea!) rather than remain dogmatically ignorant in religion (boo!). You should be able to find it on the shelf at your local Strawmen'R'Us.
