Transformation is progress. Until it implodes.

Pursued across the globe by the forces of a shadowy, unknown enemy, the warriors of the Medici Protectorate face their most dangerous challenge yet in the defense of the Notaro sisters, the secret legacy of the ancient Medici line.

Nico Micelli shows the world a calm, mild-mannered personality, but under the surface simmers ferocious passions he struggles to suppress. To say he has a wild side is an understatement. As his work with the Brotherhood intensifies, he finds it increasingly difficult to temper his emotions. It doesn't help that his charge continuously tests his limits.

Donni Notaro lives under Nico's protection. She and her sisters are in constant danger simply because of their ancestry. Without the protection of the Brothers, their lives would have been forfeit long ago. But that security comes with a cost—her freedom. Essentially sequestered, she becomes Nico's shadow, her clandestine pursuits putting both of them in peril.

To defeat their foes, Nico must not only acknowledge his wild side, he must thoroughly embrace it. But the transformation may take him down a path he can never return from.
