Veyron by Roger Scouton

London Insurers gives Jack and Amber the cakewalk assignment of merely monitoring security provided by others at the Marine Corps Warriors Hospice Car Rally from El Tovar Lodge on the South Rim of The Grand Canyon to the finish line in Sedona. The working vacation quickly heats up when a trail of dead racers is discovered. London instructs Amber and Jack to solve the crime. The search goes smoothly until Jack and Amber become the hunted, running for their lives in the mountains of Arizona.
