Introducing... Auraria by Tim Westover

Introducing books through the first paragraph or so...

Holtzclaw hadn’t heard of Auraria until his employer sent him to destroy it. The tiny town, nestled into the curve of an unimportant mountain river, had no reputation among capitalists or tourists, but even insignificant places can be expensive to acquire. Holtzclaw rechecked his traveling bag—all the money was still there. The thousands of dollars in federal notes were just ordinary paper, but the gold coins were the strangest he had ever seen. Instead of eagles and shields, the coins were stamped with images of bumblebees, terrapins, chestnut trees, and indistinct figures by a stream. The figures might have been bathing or even panning for gold; they were too small to tell. Shadburn had said the coins were minted in Auraria from local metal. The gold was returning to its source.
