After a few days of not being able to work on the layout, I finished it today! Huzzah!
Ordinarily I would go ahead and print it out and proof it and then find some really tiny mistakes and then input those corrections into both the layout and the e-books. But, man, those LibraryThing reviews! Even people who had issues with Trang want to read the next book ASAP. So I think I'm bumping Trust up to top priority, with the large-print edition of Trang downgraded to being the project I work on when I haven't had any sleep.
