An audience-directed story, as far as I know, is something I made up. I was inspired by the Choose Your Own Adventure stories I used to read as a kid. The series allowed the reader to make a choice at the end of a page or scene, and that choice would ultimately change the outcome of the story. You can still find Choose Your Own Adventure and other similar reader-directed stories in bookstores and online today.
I truly enjoy that style of book, and I delight in group participation. I love to know what people think and I love being surprised by stories. So I developed my own little thing that gives me both—the audience-directed story.
Installments for my audience-directed stories are posted on my website four times a year, in October, January, April, and July. For one month after posting, readers can vote on the outcome. Only after all the votes are tallied do I begin work on the next installment.
