This has nothing to do with the above post... I am in the process of reading your book online. I stumbled across it while randomly googling x-ray pictures (I find them intriging). I absolutely love it! I can't pull myself away! You now have yourself a dedicated reader who will be checking your blog everyday. Keep up the great writing and never stop caring. PS - No worries, I plan on purchasing your book regardless of whether or not I've read it all online.
