Abducted to Breed

When his sister vanishes on her way to school one morning her brother, Henry Russell, a detective in the Santa Monica police dedicates himself to the task of looking for her and any other missing persons, and becomes renown as such. Although five years had elapsed since Amy had vanished without a trace, he never gives up hope of someday finding her.
He retires from the police to open his own detective agency after receiving a contract from the FBI to search for missing persons. On his last day on the job, as had been his custom for the past five years, he searches various police departments' computer systems for live or dead Jane Doe's, the term used to name an unidentified woman, and nearly faints when Amy's face appears on the screen--five years older but it is deninitely that of his sister.
Henry calls a detective friend at the Bakersfield, California, police department, and asks him for details on Jane Doe #48. It seems that she was discovered in the back of a trailer when the truck driver checked his load--nearly dead from loss of blood due to an amputated hand, about five months pregnant, and suffering from total amnesia.Upon hearing the details, Henry drives to Bakersfield to verify that the young woman is indeed his sister, and finds out that he was right and that it is her.
Amy does not recognize Henty at first, but once she does she tells him what had happened to her after she was kidnapped. It's a horrific story, about being kept caged for five years and seriving as a breeding mare together with other women, for what she was sure was a high priced adoption agency. She had no idea where she was kept but was sure that it was somewhere in the South. She was finally able to escape by hacking off her cuffed hand when she found a firewook chopping ax.
Using some of Amy's details and descriptions, Henry and the crew that he quickly assembles manage to trace the kidnappers and brings them to justice while rescuing all the women captives used in the reprehensible operation.
