Wooding has spoken of delays to the sequel caused by his work on video game projects such as Assassin's Creed: Valhalla. In March he reported the novel was on temporary hold, indicating it might be a while before it could come out. It's therefore a bit of a surprise that it's now done and with the editors.
The Ember Blade was an accomplished "classic throwback" epic fantasy written with Wooding's customary verve and humour. I look forwards to the sequel, and finding out what the "secret project" he was working on, which briefly took precedence.
