Your first fantasy book, of course! What did you think I was asking? HMMMM?
Or, how did you come to fantasy reading? I suspect our first foray into fantasy may have been the fairy tale. But, later, when you got a library card what brought you to the genre (I am lumping fantasy, PNR, fantasy erotica, etc. together for expediency)? Was it a book, TV show, film? Did you love it as a kid or teen and then trade it in for what some people see as more serious literature (did you catch my snark?)?
I can cite a couple of things:
1. The original Star Trek, in syndication, and my MAD crush on Captain Kirk.
How totally embarrassing. This got me into Sci Fi and reading the classic: Ray Bradbury, Kurt Vonnegut, Pohl Anderson (?)…
2. Fantasy Literature courses in college. I never did get through the Thomas Mallory, but I loved the roots of fantasy literature and when I was serious Jorge Luis Borges. I still recall a story he wrote — I believe it was called The Circle, about mankind creating itself from itself.
3. LOTR – The movies, Harry Potter and most recently Twilight.
