Venture Deals (by Brad Feld) provides a great overview of startup finance matters. It is intended for founders and covers things other than employee equity. It’s an extremely useful read because it provides a holistic overview of the overall fundraising process and enables one to think about equity in a systematic way.
The new book Secrets of Sand Hill Road by Scott Kupor is slightly newer, a little more readable, and talks a lot about dilution, but otherwise covers almost the same ground.
Both books are great in understanding the space and motivations of various players.
That’s another great one! I would suggest reading the Venture Deals (which appeared quite practical to me) first and following it up with the Secrets (that’s great for understanding incentive structures and motivations of everyone involved).
