I also use Scrivener as my writing software, and Scrivener has a cork board feature which I use extensively. That said, there's something about physically seeing all of my chapters and scenes in order, and being able to move them around in a physical space, that I find very helpful.
Fear the Stars comes out in about seven weeks! I've already started getting my advanced copies from my publisher, and I have to say I'm very excited about this book. I realize I say that every time, but I honestly think it's because of a positive trend in my novel-writing abilities as opposed to any bias on my part (I mean, let's be clear, there's that, too, but still).
If I were to rank my Chaos Queen novels, I actually think Duskfall and Dark Immolation are about on the same level. They're very different novels, with very different strengths and weaknesses, but if I had to grade them on a whole I'd say they're of roughly the same quality (which is, in my opinion, pretty good quality). I think Blood Requiem, on the other hand, is clearly superior to the first two novels in the series. It's tighter, the characterization and character voices are stronger, and overall the writing is just better.
I think Fear the Stars is to Blood Requiem what Blood Requiem was to the first two books in the series: tighter, stronger, better. That's a good thing for a number of reasons, but mainly in that I think it's displaying how I'm generally getting a better grasp on what it means to be a writer. That's a trend I hope continues throughout my career.
As far as Dawnrise goes, it definitely has the potential to be my best book yet. It might end up being more or less on par with Fear the Stars, or, perhaps, just a smidge lower (I really did like FtS, ya'll). Only time will tell, of course, but based on my outline and what I've written so far, I'm feeling very confident about the ending book of the series.
