When the Dubois investigation turns up an unexpected connection to the Russian mob, Luna finds herself heading down a terrifying path of no return. Soon she is held captive by the very evil she hunts-one that reaches far across the borders of Nocturne City to the seedy brothels of Europe and beyond. Now, with street smarts, seduction, and a sixth-sense for danger as her only weapons, Luna will enlist the help of her former lover Dmitri-who has his own reasons for bringing down this crime ring-and risk it all in the ultimate showdown.
