This was a collaboration with Claude.ai, but a bit different from my usual. I had a chat going covering several aspects of the final stretch of the book: dictation cleanup, brainstorming and revision thoughts (basically me feeding it my revisions and seeing if it caught anything obviously wrong like typos, awkward sentences or me losing track of the characters’ movements). The reference docs included a summary of our previous chat, covering the “darkest hour” stretch of the book. Claude’s cheerleading had been very helpful through both these stretches of story, which were difficult to write. I fed the blurbs from the past two books into this chat (which had gotten long enough in terms of total tokens to where Anthropic was throttling it every few messages for a couple of hours). Claude naturally focused way too much on the spoilery third act it knew best, so I had to summarize the earlier stages of the story for it. It then gave me a rough draft I could use, and we went through several rounds of me tweaking it, asking the AI for feedback from a book marketing POV, and me tweaking it some more. The final (for now) version is below the cut, with human text in bold. The taglines for each character are carryovers from earlier blurbs, and have been italicized.
