Smouldering embers threaten to ignite the flames of war, and the secret power lurking behind the throne is fanning the fire, pushing two nations toward the brink. With a longtime peace about to be reduced to ash, Av'ry March, conman turned investigator, must find a way to quench the hostilities. Of course, when he made that final promise to his late partner, he hadn't actually known it meant he would have to stop a war. But it was too late to worry about that now. With the help of a spy whose daggers are as sharp as her tongue, and an escaped slave with murky origins, he must rush to uncover the true motivations behind the conflict in time to turn the tide.  This unlikely trio's quest will lead them in search of the forbidden secrets of the dragons, ancient beings that vanished from the world a thousand years ago, and a powerful relic that has been intentionally lost to time. As they delve deeper into the mystery, they will face assassins, jealous gods, cunning demons and their own pasts, only to discover that what they are seeking threatens much more than just the peace between two nations.  With the fate of humanity hanging in the balance, will they accept the destiny laid out before them, or forge their own path in a desperate attempt to alter the outcome? After all, it only takes one spark to set the world aflame.
