Where I find myself right now is in short story mode, writing some prequel stories that are likely to be foundation for the first book in my next series. Vivienne is taking over from Olivia in my headspace, and Vivienne's mother, Rosalie, is the one talking to me of late.
As folks read Brigitte's Cross, I'll be excited to hear how the reader's perception of Olivia changes. Book Three is percolating alongside the first ideas for the series that follows the Garnier family.
I may play, too, with some other Olivia short stories at some point, but she's just not where my head is at the moment. I'm sure she'll start bugging me again soon enough.
