I missed this blog post when it went up on the 21st, but saw it earlier today. Tor UK has dropped the line, so the last two books remain unwritten. These dark, procedural UF novels are excellent and I was so excited to read the next one. They are desolate and hopeful and one has a fucking Neil Gaiman cameo.
I would be more saddened, but the cover art rework and the format change to a paperback release for the third book make this also not terribly surprising.
If anyone sees him doing some crowd funding to finish the series, please let me know. I will definitely throw money at him for two more books.
