I had an interesting email from a reader about the killing in Chapter 8 via peanut oil. It turns out that highly refined peanut oil probably won't cause the anaphylactic response indicated. However, further research shows that raw or unrefined oil certainly will. I simply added the word 'raw' to the killing method. No problem.
Book 2 differs from Book 1 in that in almost all cases the story proceeds chronologically. With very few exceptions, there will be no bouncing back and forth in time. Some people liked it, some people didn't, but it mostly ended with Book 1.
Chapter 10 is relatively short, but that's the way it works out sometimes. Sorry about that. Chapters break as required by what is being covered, not by a minimum word count.
