In a world where fairy lives are traded for miracles, a river trader receives a mysterious job that could change the shape of his world forever in this thrilling young adult fantasy from New York Times bestselling author Scott Reintgen.

Kill a fairy, get a miracle. That was the cruel logic behind the Bloody Exchange, and there is no miracle greater than the River Infinite?an entire river, born in seconds. The waterway runs in an impossible circle, carving out new trade routes and birthing new cities.

Less than a decade later, Truce works the river with his best friend, Shaw. The two have become the fastest and most reliable smugglers in the business. Every successful trade or quick-thinking con has them one step closer to a better life. Their next job? Transport an undisclosed package.

But when they arrive, they discover the package is not a what, but a who. And with miracle hunters trailing them, Truce and Shaw will need to move more carefully than ever. Because this time, a successful journey won't just mean a little more coin in their pockets?it might reshape the entire world as they know it.
