A Strong Tower - first comments

I just got comments back from my first alpha reader and learned two things:

• Alpha readers really help to improve an author's writing.  Verb tenses, clarifying who's speaking, I had a "well-stocked bookstore" several hundred years before Gutenberg.  Thank you, +Esther Morrow.
• Google Docs is a really good medium to share chapters and get very detailed comments back.  It's easy to interact with them.  Nice job, Google.
