Jools Warner

Jools Warner is a tarot nerd from Saturn, and author of Ernie and the Mage-Killer. Starting out her current incarnation in a succession of unassuming English towns, early creative experiments fell by the wayside when the depression kicked in and refused to budge for quite some time. Story-writing was forsaken altogether, which was a bit silly, to be honest; it could have been rather helpful. Academic successes led to a Ph.D in Death Studies (yes, really) and a career in said field. Realising later, however, as a person sometimes does, that this was not what she really wanted to do, and wondering whatever happened to that whole writing thing, she took decisive steps. Wrestling with self-doubt, Jools wrote words, and then more words, qualified as a Yoga instructor, left academia, did an MA in Creative Writing, turned professional with the tarot thing, and wrote even more words. She lives atop a hill in Sheffield, UK, sharing her home with two cats, one of whom is really bureaucratic.
