Calvin Hight Allen

As Isaac Allen grew up, he learned to love working with his hands, and eventually became a builder. In the process, he, his father Calvin Allen, and his mother Maria Fire formed an unofficial yet very productive construction company -- Eyeball.

Dan Weaver is a headhunter who specializes in construction searches. When a young mother tries to talk him into a different type of search -- looking for her engineer-husband who's gone missing in the wilds of Canada, Dan is reluctant. He's got his own wife, his own life in Asheville, North Carolina. However, the more he hears about the mysterious disappearance of this young engineer, the more intrigued he becomes.
