I spent a lot of time in my academic life writing about borderlands. I had a real love/hate/and then total love relationship with Gloria Anzaldúa’s Le Fronterra. I obsessed for a while about literature involving Northern Ireland, my dissertation was about the way in which Anglo-Irish characters in the early Irish novel had to skirt a border between playing the “native” and seeking respectability in social circles that would allow them to champion Irish causes. So it’s no wonder that my book is so obsessed with exploring boundaries, borders, and borderlands. For me, the metaphor comes into play with the border between the “underworld” of the fairies and the mortal world. Like most folks, I had a vague understanding of Irish mythology and folklore before traveling to Ireland, but what I didn’t know was how this demarcation between the mortal world and this super magical world came about.
