Am about to dive into revising Part II, with a major change -- I realized that in my first draft, I took my antagonist out for a while with an injury, and there was really no good reason for that -- it actually decreased tension and slowed down the book. Much better if the injury hits the protagonist's strongest helper, ramping the tension up instead. What was I thinking before? Answer: I wasn't thinking, just writing in a rambly sort of way. Sometimes that works for me, but sometimes, my subconscious is not actually as effective as my conscious.
