In case you wanted a peek at what I've been writing, my logline and first page for book #1 are up for critique here:
I don't use actual photos, or picture a specific person or actor when I'm writing a character, but lately, every time my husband was watching Fringe on TV, I was struck by how the two main characters on that show remind me of the hero and heroine in my book. So, this is kind of how I picture my Josh and Kate now. This could be a picture of them walking through NYC together.
I don't always picture my characters, but I do love to picture what my book cover might look like. I think Julie James has the most gorgeous covers, don't you?
Anyway, enjoy! :)
