EC contracted Painted Promise, an SF erotic romance.  It was the first sub to a new editor, so I was knuckle-gnawing at this one, lol  Here’s the unofficial blurb:

Thirza Girard is a clone.  Her mirror image founded a thousand year dynasty that spans the quadrant.  The Girard family power is no accident.  The original Thirza did a deal with an alien, a Tashen-Dar, who could manipulate probability.  He changed reality so that Thirza and her descendants are favoured with opportunity, the chance, if they grab it, of achieving great wealth and power. However, it comes at a cost.

Paint – an organic technology – binds the alien, Zaid, in the bowels of the planet. Paint has captured him as an image for a thousand years.  The time of binding is almost at an end and Thirza Girard’s clone must pay the price for the power her family has enjoyed.  She must rebind him, capture him again in paint, or pay another, more carnal price.
