These are great and really get your mind thinking about alternatives to what most people believe.
- Sarah Lacy's Once your lucky, twice you're good. http://www.amazon.com/Once-Youre-Lucky-Twice-Good/dp/1592403...
This isn't a technical book, but can really get you motivated to succeed reading the stories of previous successes! It also gives a bit of an insight into the internal workings of a start up in the early stages. It highlights networking as an important factor!

This book was quite good, but felt a bit dated in comparison to Rob Walling's 'Start up book'.
Finally 'Founders at work' is definitely worth a read. http://www.amazon.com/Founders-Work-Stories-Startups-Problem...

I've read quite a few and where some are in sightful / useful when scaled or when funded, this book is the best I've read for a typical software developer to have a successful start up business!
It is also written by a fellow HN'er Rob Walling - so you know it'll be full of great information! Check out his blog 'SoftwarebyRob' for a taster.
