Conjure Man — Cyn Bagley

"In the time before this one, we emerged from the third world to here--the fourth world," the shaman stopped speaking and listened to the sounds outside. "We never speak of this in the summer when the Snake people are active."

The children nodded their heads and waited quietly as the fire rose in the center of the Hogan. The children had come home from boarding school. It is what it is, thought the shaman. Soon these children would tell their history to their children. Much of it would be lost. Some of it would make it to the future, when the snake people had enough power to open the cave.

He continued with the story and the blessing.
 
One hundred years later, a tree, a cave, and four seeds appear in a world of technology and serial killers. Tessa and her lover Taylor are only part-breed Navajos, who have lived most of their lives off the reservation. They have heard pieces of the creation myths so are unprepared when they are pulled into a myth. How could it be true? Myths have no power in this world.

Their enemy, Luce, a conjure man and ally of the Snake people, knows who they are. He uses a dimensional rift between the world to bring his allies here. He wants to rend, tear and subjugate.

Four seed-bearers are the only ones who can stand in his way. But Luce has the ancient wisdom and the ancient allies.
