A quatrain leads Cade to a rural area where a best-selling psychiatrist is helping people to to deal with alien encounters through hypnotic regression. Posing as a new member, he reaches out to the others in the group and investigates the psychiatrist -- who seems to be using the group as fodder for her next best-seller. He is convinced that the Gua are controlling the group for their own purposes -- but is it the doctor or one of the members in therapy? Along the way he grapples with the return of the Hannah clone, and helps out a young couple who were victims of another Gua experiment. He finds out that their memories have been tampered with by the Gua and uses a relaxation technique to help learn what really happened to them.
