The Washington Times book review stated this about Sheehan and his new novel:
"Sheehan has a worldly experience that is unrivaled. His descriptions of Asia and the Artic are intense and real. He has worked on many international trade projects, and his experiences have led him to Libya, South America, Russia and The People’s Republic of China. He has worked with governments worldwide. Though now living outside of New York and working in the private sector, he has brought every element of his experience to his first novel.
This is a page-turner with a fascinating and powerful story line. Fans of adventure, intrigue and mysteries should seek it out immediately."
