In a world where an industrial revolution is powered by magic, Tyen, a student of archaeology, unearths a sentient book called Vella. Once a young sorcerer-bookbinder, Vella was transformed into a useful tool by one of the greatest sorcerers of history. Since then she has been collecting information, including a vital clue to the disaster Tyen’s world faces.
Elsewhere, in a land ruled by the priests, Rielle the dyer’s daughter has been taught that to use magic is to steal from the Angels. Yet she knows she has a talent for it, and that there is a corrupter in the city willing to teach her how to use it – should she dare to risk the Angels’ wrath.
Yet not everything is as Tyen and Rielle have been raised to believe. Not the nature of magic, nor the laws of their lands… and not even the people they trust.
Further away, a people called the Travellers live their entire lives on the move, trading goods from one world to another. They know that each world has its own store of magic, reducing or increasing a sorcerer’s abilities, so that if one entered a weak world they may be unable to leave it again. Each family maintains a safe trading route passed down through countless generations and modified whenever local strife makes visiting dangerous. But this is not the only knowledge the Travellers store within their stories and songs, collected over millennia spent roaming the universe. They know a great change is due, and that change brings both loss and opportunity.
