Vrath is inspired by a famous character from the Indian epic Mahabharata, which was the starting point and inspiration for a part of Upon a Burning Throne. I was going to write him pretty much as he appears in the novel, which is as a strong supporting character. But I wanted to know more about him than I found in the Mahabharata or any other source.

It will come as no surprise that beginning as a child, I loved wolves. I had a couple of picture books about wolves and I also got Very Upset when they were cast as the bad guys in so many things. Some early influential reads were The Changeling Prince by Vivian Vande Velde; Julie of the Wolves by Jean Craighead George; I read White Fang at way too young an age.

The Bolton Strid is a real place that really exists and I really want to go there, except for the part where I am a fairly clumsy person and I would very shortly be swept away forever, and my friends would miss me. So the story started with the Strid.

I wanted to be vague about what the spells do and what type of monster these women are, but all the details are based on folklore from Slovenia and neighboring regions. There really is a traditional creature that splits in two and hops around leaving a single footprint! “Novak” is a Slovenian name meaning “new,” which the family got because they used to move around a lot and were newcomers wherever they lived.

As I began writing this story, my uncle was dying. My father’s family is from Mexico and sometimes they practice interesting ancestral medicine. One of the treatments for cancer and leprosy involves boiling a vulture, bones and all, down to a thick stew and making the sick person eat it. A tía from Mexico somehow caught a vulture, killed it, and fed vulture stew to my dying uncle. I was trying to explain to a bewildered friend the reasoning.
