This is novel 2 of the series Walk-In. Dave Madison died of a massive heart attack. He woke up in a hospital as James Jackson. James had committed suicide by taking pain killers. His roommate found him in time and called 911. He had committed suicide since he was in love with a young woman who treated him badly. The new James was a combination of three spirits; the man who died of old age, Dave who died of a heart attack, and James who died from a broken heart.
James was rich and soon was involved with a couple of young women that were going to his college with him in Arizona. They moved in with him which made him happy and gave him plenty of affection. He was only 18 years old and had three masters' degrees and was working on his doctor degree in computer science. He was a child prodigy and started school when he was in his early teens. He worked on another masters' degree while he worked on his doctorate.
James got his doctorate in computer science and was offered a job repairing computers at Las Cruces, New Mexico. He moved there and took his two women roommates with him. He got a professor position at the College which allowed him to meet a lot of new women. This set him on the road to get his twelve wives.
