Dr. Sonjie Tuumlar has the world in her hands, literally. She has to make sure two cyborgs, C-A-I-N and A-B-E-L, are fit enough to fight against Earth's attackers. Her focus shifts when both men desire her. Determined not to be like her former lover, Dr. Lars Urlean, she fights to not have a sexual relationship with her creations. However with a man as obliging as A-B-E-L and as seductively dangerous as C-A-I-N, will she be able to hold out, or will she succumb to one of the two men...or both?
