I don't have a particular story that kicked me off into the writing world. Before I could read and write my imagination created various stories, my mother read to me every night and I learned through her to love the written word. When I could read on my own I read as much as I could. In second grade I read over a thousand books for a book worm club. In third grade I read Trumpet of the Swan as my first novel length book and loved it. After reading that one I couldn't read smaller and simpler books as much, I wanted those fuller stories. I started reading Nancy Drew and the Hardy Boys, reading all but one in both of the original series and most in the newer ones. That's a lot of books! Then I delved into Anne McCaffery. I fell in love with dragons at that point with her Pern Series.
Then we read A Wrinkle in Time in fourth grade, the imagery in that book is a beauty in and of itself. After that I started ready Michael Critchon, John Grisham, and Mary Higgens Clark. And it spread out from there, I read widely, touching upon most genres and found I loved them all. I had been writing poetry and short stories, having one published when I was ten, as well as three composition books compliments of teachers. I started my first novel when I was twelve. I look back and it was a sad attempt, but it wasn't all horrible. I jotted down about 7 story ideas between that and seventeen when I finally got serious. I completed the first draft when I was seventeen, took the first sixty pages and made a 400 page novel out of it, which died a sad death through PA. As well as my second book completed when I was 21.
So one book didn't really do it for me. I have always been a writer and a story teller. It's part of who I am, always has been and always will be.
