Chris Wooding has announced that the forthcoming fourth novel in the Tales of the Ketty Jay steampunk airship series, The Ace of Skulls, will be the final book in the series. Originally Chris had planned to write a series of self-contained adventures with a few continuing elements, but during the fourth book discovered that the number of continuing storylines he'd built up had become larger than he'd planned. He's chosen to end the story definitively rather than risk it sprawling out of control across numerous volumes.
No word on what his next project will be post-Ketty Jay, but Wooding is also working on a 'remastered' ebook version of his earlier Broken Sky series of anime-influenced short novels. Wooding will be self-publishing these books himself in Kindle and ePub formats, with a date still to be decided.
Good news on the Broken Sky situation, but the conclusion of the Ketty Jay sequence will be a sad day. Still, better for the author to finish it on his own terms rather than drag it out for years for financial gain.
