My first book was non fiction/memoir. I found an agent quickly, but he couldn't place it. One editor at Doubleday said he liked the writing and would be interested if I ever wanted to try fiction, so I wrote a thriller/mystery. It sold to St. Martin's in two months. Then a sequel, which the agent didn't like, so I approached my original editor directly and sold it to her. Then I stopped writing for 15 years,
Fast forward. Wrote my urban fantasy, Dog Days, in about nine months. Confidently sent queries off to agents (my original agent had long retired) To my surprise, query was rejected. Several more, same result. Some partials, same result. Requests for full, encouraging praise, no offers.
Began to realize that getting published, or even represented, is harder than it used to be. Had one tentative offer by an agency, legit, that after further research, I passed on. One of my more difficult decisions, but in hindsight, the right one.
Took nearly a year to find representation and sign a contract, but my current agent then sold the book, plus sequel, to Ace within a month of submitting. It will be out November 2007.
