Secrets of the Serpent's Heart - N. S. Wikarski - Bog

During the untold millennia before patriarchy was conceived, the world was a very different place. Nothing concealed stays buried forever.
THE ARKANA SERIES
The forgotten past refuses to stay buried in an artifact hunt spanning continents, centuries, and lost civilizations. The prize is a cache of myth-busting relics that could rewrite history or end it completely. When a secret society squares off against a ruthless fundamentalist cult, only one faction can win. More importantly, only one will survive.
Volume 6 - Secrets of the Serpent's Heart
In SECRETS OF THE SERPENT'S HEART, two Arkana agents search the length and breadth of China for an obscure relic that will name the hiding place of their most sought-after prize. At the same time, a third agent tackles the dangerous mission of discovering the Nephilim's end game. In the remote reaches of Yunnan province, the agents encounter an enigmatic stranger who holds the power to stop their quest dead in its tracks. Meanwhile, unthinkable catastrophes befall the Arkana's leadership, leaving the secret society one step away from collapse. The serpent's heart hides more than a clue to a lost artifact. It offers the only means to save the Arkana from total destruction.
