Dragonfall
(Book)

"Long ago, humans betrayed dragons, stealing their magic and banishing them to a dying world. Centuries later, their descendants worship dragons as gods. But the 'gods' remember, and they do not forgive. Thief Arcady scrapes a living on the streets of Vatra. Desperate, Arcady steals a powerful artifact from the bones of the Plaguebringer, the most hated person in Lumet history. Only Arcady knows the artifact's magic holds the key to a new life among the nobles at court and a chance for revenge. The spell connects to Everen, the last male dragon foretold to save his kind, dragging him through the Veil. Disguised as a human, Everen soon learns that to regain his true power and form and fulfil his destiny, he only needs to convince one little thief to trust him enough to bond completely--body, mind, and soul—and then kill them. Yet the closer the two become, the greater the risk both their worlds will shatter." --publisher's website.
