Note: Originally scheduled for August 2018 publication, but per the author's blog a first draft was not completed until September 2018. In May 2019, a further blog post stated that "Prince of Glass is complete and in with the publisher now. There will be a rewrite (which is far less painful than a first draft) and some tweaking and other procedural matters...". As of November 2020, no publications appear to have been released; Amazon.com lists the US trade paperback with a release date of 2020-12-29, but this appears to be a placeholder value, as the title is not listed on the Orbit US or UK websites.
