Phantom Shadows discussion

Any ideas on which Immortal is at the center of this third book, in the series? The hints from the 2nd book, if they indeed were hints, would cause me to think it will be Bastien (and Dr. Lipton). Has anyone heard anything?

Dianne confirmed that the hero will be Bastien... but she didn´t said anything about the heroine....
I really want it to be Dr. Lipton.

I agree with both. It seemed to be the indications from the previous story, but I wasn't sure if that was her intention. I'm good with that.
