This is the third book in the Dig Deep Series with well-developed characters. Oliver is a germaphobe/Klotz Archeologist. Reyland is a singer turned construction worker. He was also the catalyst in working against the Archeologist/Museum in books 1 & 2. In this book, the two teams up to get everyone to work together. The chemistry between these two is electric. I could not put the book down. The narration was very well done.
