Fortune's Dragon — Meara Platt

You will meet a dragon who will eat your heart. This is the fortune young Faith Boscombe believes she is told by a fortune teller at the Scarborough fair. But Caleb Brayden, the boy who finds her and returns her safely to her governess after Faith runs off through the fair in tears, gives her a dragon amulet as protection. He's made up a fable about the power of the amulet, but when he happens to return to the Scarborough fair ten years later, this time as a battle-hardened general in the king's dragoons, he realizes their fortunes are bound to each other... and so are their hearts.
