Suri loves monsters--studying their lore, telling stories about them (for a fee), and--she hopes--one day taming them. Unfortunately, no one takes an orphan street-urchin who travels with a merchant camp very seriously. But Suri's self-confidence, cleverness, and ambition serve her well when a mysterious new wagon joins her camp--holding something very big, very loud, and very monstrous.

And that's before Suri runs afoul of a treacherous family with its own beastly secret--and a prince hunting the greatest monster of all.
