Killer Instinct by Joseph Finder

This book is a few years old, but I saw it on Wilbor (audiobook site) and decided it sounded good. And it was! The plot itself has been used before and I wasn't surprised at the ending. However, it was well written (and read!) and kept my interest throughout. Jason is a salesman for the Entronics company. He is happily married and they are expecting their first child. One day Jason has a car accident. The tow-truck driver is Kurt, a former Special Forces soldier, who is towing for a friend's company. Kurt and Jason end up forming a friendship which eventually leads to Kurt getting a job at Jason's company. Suddenly things start going really well for Jason at work. Seems he has sold his soul and doesn't even know it! A good suspense novel without the gore!
