TBH, don't read books, go start something. Then, when you're totally baffled by what's happening, use books to try and understand why.

Now, since you're probably not going to take my advice, I think a new book that you'll find helpful would be Startup Opportunities https://www.amazon.com/Startup-Opportunities-Know-When-Quit/...

I also recently curated a list of classic startup books on Product Hunt: http://www.producthunt.com/ericries/collections/classic-star...
