Spin by Demelza Carlton

A miller's daughter. A cursed knight. The power of a name.
Once upon a time…
Molina has one desire: to see her inventions spread throughout the kingdom. When Prince Lubos offers to take her to the capital as his bride, she jumps at the chance.
But impressing the king may take more than a simple spinning wheel. To marry Prince Lubos, she will need to work a miracle.
Molina enters into a desperate bargain with a mysterious man who turns all he touches into gold. A man with a tragic tale of his own, all tied up in his family name.
The future hangs in the balance, but will either of them live to see it?
