Best business/legal books for first-time founders?

Looking for book recommendations. Not the typical "hustle porn" startup books but actual useful stuff about business law, contracts, incorporation, etc. What actually helped you?

For anyone interested in the legal side, I'd also recommend checking out the free templates and guides on this site. Found them more practical than any book for actual contract stuff I needed day to day.

That said, "The Entrepreneurs Guide to Business Law" mentioned above is solid for understanding the WHY behind legal concepts fwiw.
