It’s a really good read. Some of the material is specific to US law, but mostly it’s a very good primer for what kinds of things you need to think about up front when starting a company, or getting into contract discussions with a publisher. It should be required reading for anyone looking to start a company.
As the author says at one point early on, it’s not going relieve you of the need to get a lawyer, but it will let you talk intelligently to the one you do get… which will save you money and get you better results.
I have a bunch of books that I’ve purchased and read in the last year, I’ll try to get a list of em up, with some Amazon links.
