Before The Great Zoo of ChinaEdit
As children, Cassandra Jane's father often took her and her younger brother Hamish camping, and taught them many survival skills and how to speak Mandarin. CJ's mother would give her daughter the nickname of Chipmunk.
At some point, CJ worked for National Geographic under Don Grover, doing full articles on herpetology-related stories, occasionally having her brother accompany her as a photographer.
During her time working at the San Francisco Zoo, CJ went out with fellow herpetology expert Ben Patrick, however she was disappointed with the date because all Ben talked about was himself, and did not invite a second date. She eventually became engaged to a man named Troy.
While rescuing a young boy who had fallen into a saltwater crocodile enclosure, CJ received several scars on the left-hand side of her face. After waking up in hospital two weeks later, the horrified Troy abruptly ended their engagement simply because of the scars she received on the left hand side of her face. As a result of the incident, CJ transferred to the veterinarian department to avoid constant work with crocodiles.
- Like most of the other leading characters of Reilly's novels, CJ has a defining feature; in this case, the criss-crossing scars on the left side of her face.
- CJ is the first female main protagonist to appear in any of Reilly's novels.
