Black Sun (Between Earth and Sky, #1)

The first book in the Between Earth and Sky trilogy, inspired by the civilizations of the Pre-Columbian Americas and woven into a tale of celestial prophecies, political intrigue, and forbidden magic.

A god will return
When the earth and sky converge
Under the black sun

In the holy city of Tova, the winter solstice is usually a time for celebration and renewal, but this year it coincides with a solar eclipse, a rare celestial event proscribed by the Sun Priest as an unbalancing of the world.

Meanwhile, a ship launches from a distant city bound for Tova and set to arrive on the solstice. The captain of the ship, Xiala, is a disgraced Teek whose song can calm the waters around her as easily as it can warp a man’s mind. Her ship carries one passenger. Described as harmless, the passenger, Serapio, is a young man, blind, scarred, and cloaked in destiny. As Xiala well knows, when a man is described as harmless, he usually ends up being a villain.
