Crystal: The Working Girls Book 3

Ever since Sativa Marano's sister died in car accident, Sativa has been searching for the necklace her sister died trying to save. But the necklace has fallen into the hands of the most dangerous villain in the world: The Silver Ghost. The necklace has the destructive power for the Silver Ghost to wipe out everyone Sativa cares about unless she can get it back.
Although she starts out this journey alone, Sativa meets many others along the way - Benjy, a strange, lonely boy who might turn out to be an enemy; Elias, a Russian spy with a dark past; and Donovan, someone linked to Sativa's sister in a way that she could never have imagined.
Join Sativa in the danger, the heartbreak, and the excitement as she struggles to keep her entire world from being destroyed.
