I'm wrapping up the final chapter on The Golden Griffin this weekend. My cover artist should be producing something in the next few days. To my loyal readers of The Dark Citadel series, thank you for being patient. It's coming, I promise.
As to why this book has taken so long, the answer is complicated. I had written pretty much an entire draft, but it took a dark and unsatisfying turn and I didn't know how to work my way out of it. Then, as I took a break to work on other stuff, including the books that people were paying me to write (The Righteous series), and other stuff with more commercial potential and/or were bugging me to come out.
By the time I came back to the Dark Citadel series this spring, what I'd written had gone cold. I had to reimagine some things. Ultimately, I decided that some of what I'd written could be saved, some junked, and some moved on to the next volume. Meanwhile, I brought the focus of the book in a little tighter. I think my readers will like it, and I feel like I'm on a much stronger path going forward.
I'm also hoping with the third volume that sales of the series will pick up a little. There's no question that better sales will make it easier to write the next chapter of the saga sooner. Otherwise, I have to spend more time working on stories that help pay the bills.
