I’ve switched the working title of the current book in the Caewen series to Sharp are the Teeth of Pearl. This is a reference to a couple things in the story, and should make sense by the end of the current novel.
I was planning for this to be the final book in the series. I’m unsure if it will be… or if it is, it will be very, very long. What I will probably do is write out and post the whole final arc, then split it in two if I need to for publishing.
