It's taking longer than I hoped for the technical review on my book to be completed. I've sent some gentle prodding, but as one reviewer put it, "The length and details of your work are daunting." So that's where the delay is coming from now. I'm going to continue waiting on that feedback because as much as I'd like to start getting some income from the book, I asked for the review because I think that's going to result in a better book going out.
