I'm reading...

...John Ringo's Live Free or Die. So far so good. The neat thing about it is Ringo's envisioned it as a kinda sorta unofficial prequel to Howard Taylor's Schlock Mercenary. This is the first in a trilogy that tells the story of how humans enter the intergalactic scene. Neat.

Update: This is a fun read, but then everything I've read by John Ringo fits that description. It's full of action, good story and characters, and funny when it's meant to be. Well worth the time spent reading it.
