When did you first learn of Louise de la Vallière?

I became interested in Louise de la Vallière while doing research on Josephine Bonaparte. There was a biography of Louise published at that time. I was curious, so I looked into it. As with Josephine, I was swept away.

Initially, I wrote a short story about her, and then I decided that it had to be a novel. I began that novel after finishing The Many Lives & Secret Sorrows of Josephine B., but put it aside about six months later when I was offered the contract for the Josephine B. Trilogy.

I put all my notes, my initial drafts, into a box to be opened when I finished The Last Great Dance on Earth. Little did I know that it would be almost six years later.
