Orope, the White Snake

Three travelers must bring a terrifying prophecy to the distant tribes of the world in the first book of this alternate Bronze Age fantasy series.
 
The nomadic tribe Whisperers of the Gods have seen the vision. The gods are preparing to send a world-destroying flood to punish those who have corrupted and forgotten the old ways. Three are chosen—Tersh, Kareth, and Sha’di—to go out and deliver a message to the world: The gods must be appeased before it’s too late.
 
Leaving her children behind, Tersh must travel to the mountain kingdom of Matawe. She must also care for Kareth, who has been told since birth that he is destined for greatness, and whose overconfidence often leads him into danger. Meanwhile, Sha’di ventures off alone to find the people of the jungle, the Petzuhallpa. And while the jungle seems like a paradise, Sha’di soon discovers the dark rituals practiced within.
 
Guided by visions, these adventurers must use their wits to survive in these strange new lands that show little interest in their warnings.
