Reading kills brain cells, and is known in the state of California to cause cancer.
They say that only about reading the Constitution.

I really dig the Posleen War Series by John Ringo. It is way Sci-Fi, but really rocking rides.
If you haven't read the Eric Flint 1634 Series, you are missing out. It is just a single sci-fi event, that takes a West VA mining town from 2000 and drops it into Germany in the middle of the 30 years war in 1634. Imagine what the tech and weapons from 2000 could do. But the quantity is limited. Really a great read. The people of the town basically make the United States happen a couple decades earlier.
I read both of these series electronically from webscription.net.
Also, a great book is Freehold from Michael Williamson. That is a free download from the site.
