80AD The Tekhen of Anuket (Bk3) by Aiki Flinthart

80AD Book 3 finds Phoenix, Jade, Marcus and Brynn trapped inside a pyramid in ancient Egypt. No Pharaohs here, this is Egypt as you've never see it. Rome has taken over and the country is far from peaceful. 

This adventure is the most insane yet. It has everything you'd expect: mummies, secret passages, treasure, an evil high priest, human sacrifice, walking undead and more. Together our four adventurers must escape the clutches of the high priest of the Egyptian god, Set and release the imprisoned goddess of the Nile, Anuket. Without Anuket, Egypt suffers endless drought and the country will die. 

An ancient prophecy predicts 'the Phoenix' to be the savior of Egypt, but our Phoenix doesn't think he's up for it. Phoenix and Jade must battle not only external enemies, but their own inner demons, as they struggle to deal with this harder, harsher Level and its new enemies. 

To make matters worse, Phoenix and Jade's old enemy, Feng Zhudai, is manipulating the Roman leader of Egypt, weaseling his way into things, trying again to upset the balance of this world by causing chaos.
