This is Ethan and Heather's story. Heather is a telepath and has been able to turn that into a career- as a FACS specialist (reading facial expressions and body language to determine if someone is lying. The other couples from previous books all make appearances. The underlying storyline with Gershon trying to start WW 3 is continued. New allies appear.
Jared (an other) and General Lane) Aidan (an older immortal- he can bear some sunlight) is the one who transformed Heather, so she is stronger than Ethan.
