I had thought the thirteenth Arch Magus novel was taking longer than usual to appear, and apparently (according to the Afterword here) it’s because the author burned out and was thinking of ending the series. They changed their mind though and this entry is kind of a transitory one centered on giving some backstory to that group of Imperial witches mentioned a few times earlier.
Michelle Sagara‘s latest Elantra novel focuses mainly on wrapping up the ‘seeing ghosts’ plotline while also tying it into and adding an addendum to the gold dragon’s backstory. Or rather, I’d like to say it focuses on that, but instead it mostly consists of chained recap segments which only eventually get around to dealing with that in a tortuously roundabout manner.
