For hundreds of years, the Blaukenev clan has wandered across Tilzam, from one end to the other and back. Each wagon carries history, love, laughter, pain, sorrow, and secrets. Their greatest secret of all may be Chavali, the clan Seer.

Spirits claim/use/save/damn her.

With her gift/curse, nothing surprises her anymore, no one keeps secrets from her. She, on the other hand, has more than enough secrets to keep. Secrets of her own, secrets of her clan, secrets of the world, secrets she even keeps from herself.

There are always people who want secrets.
Some will do anything to get what they want.

The Fallen is the foundation of the story of The Greatest Sin, of a world adrift from its God that desperately wants Her back. Chavali's comfortable, predictable life will be ripped apart and burnt to ashes as she's forced into the middle of that struggle. Change, she hates it passionately. It hates her right back.
