Check out this very nice review for Jody's Passing For Human from Bestsellers (October, 1977):
PASSING FOR HUMAN
Mgrird Nixon is the name of Brenda Starr's robot-slave. Or slaves, as she owns several hundred. But Brenda Starr is not really Brenda Starr. She is one of several spare bodies put to use by Benaroya. a 36-foot, dolphin-like extraterrestrial who is furthering her anthropological studies on earth as she hunts down the evil cosmic being who is worshipped on 11 primitive planets as the Prince of Darkness. Scott's daring and sense of pure fun makes her first novel a memorable one. a splendid blend of satire and sf adventure.
