Welcome to Paris, in 1633, where dragons menace the realm. Cardinal Richelieu, the most powerful and most feared man in France, is on his guard. He knows France is under threat, and that a secret society known as the Black Claw is conspiring against him from the heart of the greatest courts in Europe. They will strike from the shadows, and when they do the blow will be both terrible and deadly. To counter the threat, Richelieu has put his most trusted men into play: the Cardinal's Blades, led by Captain la Fargue. Six men and a woman, all of exceptional abilities and all ready to risk their lives on his command. They have saved France before, and the Cardinal is relying on them to do it again. So when la Fargue hears from a beautiful, infamous, deadly Italian spy claiming to have valuable information, he has to listen ...and when La Donna demands Cardinal Richelieu's protection before she will talk, la Fargue is even prepared to consider it. Because La Donna can name their enemy. It's a man as elusive as he is manipulative, as subtle as Richelieu himself, an exceptionally dangerous adversary: the Alchemist in the shadows ...

Welcome to seventeenth-century Paris, where intrigue, duels, and spies are rife and Cardinal Richelieu's men may be prevailed upon to risk life and limb in the name of France at a moment's notice. And with war on the horizon, the defense of the nation has never been more pressing.

Danger is rising from the south—an insidious plot that could end with a huge dragon-shaped shadow falling over France, a shadow cast by dragons quite unlike the pet dragonets that roam the cities like stray cats, or the tame wyverns men ride like horses, high over the Parisian rooftops. These dragons and their descendants are ancient, terrible, and powerful ... and their plans contain little room for the lives or freedom of men.

Cardinal Richelieu has nowhere else to turn; Captain La Fargue and his elite group of men, the Cardinal's Blades, must turn the tide. They must hold the deadly Black Claw cult at bay, root out traitors to the crown, rescue prisoners, and fulfill their mission for the Cardinal, for their country, but above all for themselves.

It's death or victory. And the victory has never been less certain.
