The Dragon's Wing Enigma

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 3 - The Dragon's Wing Enigma
In THE DRAGON'S WING ENIGMA, agents of the Arkana and the Nephilim leave no stone unturned on the island of Malta in their search for lost artifacts. The Arkana team frantically scavenges for clues among the ruined temples of the archipelago before their foes arrive to comb the same terrain. A new crisis erupts on the home front when a runaway bride seeks refuge with the Arkana. The girl is the youngest wife of the Nephilim's polygamous leader, and she may have accidentally led the Nephilim straight to the Arkana's cache of matristic artifacts. Matters come to a head in an isolated mountaintop cave when the relic hunters learn that their prize can only be discovered if they "keep true to the dragon's wing." With Nephilim operatives blocking their escape route, they may not live long enough to solve the riddle. More than treasure is at stake this time around.
