Written by the reporter who knew the murderer best, and who was the only reporter she talked to after her arrest, Human Harvest provides a rare look inside the dark life of a female serial killer, Dorothea Montalvo Puente. She operated a Sacramento, California, boarding home for Social Security recipients -- eight of whom were eventually unearthed from the small but well-manicured lawn around her Victorian home. Author Daniel Blackburn recounts the shocking story of how Puente, a kindly-looking, grandmotherly woman, freely exploited a loophole in Social Security law to accomplish her macabre deeds. Even more disturbing, perhaps, is how -- even after her arrest, conviction and incarceration -- it took the U.S. Congress more than 13 years to close that loophole.
