I highly recommend books by SM Stirling, specifically Conquistador and these trilogies (they are related)
Dies the Fire
1. Dies the Fire
2. The Protector's War
3. A Meeting at Corvallis
Change
1. The Sunrise Lands
2. The Scourge of God
3. The Sword of the Lady
Also Ken Follett has some good WWII fiction supposedly (I'm not a fan of the genre). And James Rollins' books are good suspense thrillers (start with Sandstorm).
Oh and ditto the Christopher Moore books. He's excellent. And if you like those, check out Neil Gaiman and Terry Pratchett
