Silent Obsession

Two worlds collide in the underworld of Europe.
Christian de la Cruz, ruthless boss of Spain's infamous Blackthorn Syndicate, and Nathaniel Crowe, cunning leader of England's feared Marrow Circle, have ruled their territories with iron fists-each alone, each untouchable.

But now, a threat unlike any they've faced emerges: Victor Drax, a former ally from Eastern Europe. An unpredictable and bloody-minded man who is seeking for power and aiming to seize their territories by any means necessary.

Forced into an uneasy alliance, Cristian and Nathaniel must navigate treacherous loyalties, forced to work together despite their mutual hatred for each other.
