I'll show my lack of professionalism here. After 35 years of writing for myself only, I read one of JB's books and something inside me simply screamed that I wanted to write like that. I'm not talking genre like urban fantasy here. I fell in love with his brisk, concise, compact description. I fell in love with the graphic expression and use of senses that blasted off the pages. I fell I love with his mix of distinct realistic characters--with powerful females (he likes strong women and it shows), his intense creative action, the frailty of Harry mixed with his power, his character rants on everything from the smell of hospitals to the types of fear. It's quirky and fresh with lots of snark. The plots and writing show intelligence. The speed of his delivery, while still managing to place verticality along with horizontal motion in just the perfect mix.
Since I was writing by myself and for no one, I tended to the longer descriptive work. My personal preference over my life time to gravitate to English authors. My love of English spy novels, English romances, English classics, English mysteries, English author sci fi shaped my preferences before I knew there were preferences for those things. I've been told that my historical work is on a par with Phillipa Gregory, as I've not read them I can't attest to that. But I like to get steeped into a scene.
Along comes Butcher with his short, fast paced, graphic, film noir, kick ass pages in a style that I don't see anywhere else. Yeah, I've now read a variety of urban fantasy authors and tried to find others like him.... I don't find them. Not in the intense clarity of his style. I've not explored graphic novels, but I see his style as unique and individual and unlike anything else that pops up on the best seller lists. (I'm not a fan of the Alera books, not that I think they are horrible--they just aren't unique to me like his style in the Dresden File books.)
I'd like to think we are seeing a new trend, started by Butcher that is a unique and new style of graphically written novels. Since mainstream readers don't read graphics--this is incredibly fresh and appealing to them. I hope that someday he receives the recognition that he deserves. Not easy when your preferred genre is sci fi/fantasy.
So on my journey of writing style I know that I can't, nor do I want to copy Jim Butcher. To do so would be foolish and impossible. Yet that which he does that I admire, I can explore, develop, expound, and learn.
