Hello and welcome to Wikipedia! Just to echo some of the things I already stated on other talk pages and some additional thoughts:
While it is my understanding that there is nothing preventing you from making edits to the relevant articles using your book as a source, I feel it would be better if someone else made those edits who is also familiar with the book (someone who has read it). The concern here is that without you even realizing it, you could unintentionally introduce bias into the article; or perhaps add undue weight to your own view or your book's viewpoint. I suppose you could go ahead and make some edits and see if they fly, but I personally would be hesitant to rewrite an adit on content based on a book I haven't read. It would be best if someone who is familiar with your book (someone other than yourself) would make these edits. In a nutshell, be bold and make edits, but be very careful when making edits on content that you are personally intimate with.  Thank you.
