Alas, all good things must come to an end. My cover artist of the last couple of years, Jake Bullock, got a full-time job (good for him) and is prohibited from doing freelance projects (bad for me). The good news is that I had just finished The Chained Adept series, but I already had a cover from him for book 1 of The Affinities of Magic series. So I had to start over again for that.
Happily, I've partnered with a new cover artist from Poland, Michal Wojtasik.
His audition blew me away. I only asked for a simple sketch of the scene I had in mind, and look what I got, a day later.
Needless to say, he buried his competitors.
He's completed the cover for Structures of Earth and is working on the one for book 2, Fragments of Lightning. I'll be writing book 4 before I release the first 3 books in the series, one right after another, to try and build up some momentum for the new series.
