Free-will-by-Mark-Balaguer

I have a 2000 word paper on the book Free Will by Balaguer and I really don’t understand it. The question is how does Balaguer Explain the crucial notions of being mine and of me being the author of a decision. Also does his own account of a free choice make it sufficiently clear that this is a free choice was yours, that you were the author of this choice.
