Meet the Professional.

Mafiya enforcer Aleksandr "The Siberian" Sevastyan's loyalty to his boss is unwavering, until he meets the boss's long-lost daughter, a curvy, tantalizing redhead who haunts his mind and heats his blood like no other.

In the game of obsession, two players are better than one.

From an opulent palace in Russia to the decadent playgrounds of the mega-rich in Paris, the two lovers tempt each other's boundaries to discover whether their darkest--and most forbidden--fantasies really can come true....
