Do More Faster by David Cohen and Brad Feld
I'm a big fan on Brad Feld's book of startup advice based on the TechStars experience. It's called Do More Faster: TechStars Lessons to Accelerate Your Startup by David Cohen and Brad Feld. I highly recommend it to everyone along with The Lean Startup and The Startup Owners' Manual. Brad's blog and his can be found here.
