Can anyone recommend a good one?

I've heard the best are those jazz books.

If you're getting started with theory, jazz may be overwhelming unless you can find one that starts from the very basics. For general theory I'd recommend The Complete Idiot's Guide to Music Theory.

I do have a basic knowledge.

I need something that's very...thorough.
