Katya Petrovna is a risk-taker. It's what led her to leave her job at the Russian Federal Security Service and join the new G8 Intelligence Agency. But her reputation as headstrong and independent precedes her, and G8 wonders if she's ready for their dangerous missions. When a Russian woman is caught at London Heathrow airport with a suitcase full of cash, John Hammond, G8's Director General, assigns Katya her first operation: infiltrate a Russian mafia-run casino on the Black Sea. Katya goes undercover as the daughter of a wealthy ex-KGB officer looking for a good time. But as she delves deeper into the casino's operations, she finds herself out of her depth. The mafia's reach extends all the way to a Chinese Tong Casino in Macau, where they're running a brutal trafficking operation. And with each step, Katya's mistakes put her in even more danger. She tries to recruit Kirill, a casino floor manager who she knew as a street kid in Moscow, as an informant. But as the stakes get higher and the risks greater, she can't be sure if he's on her side or working for the mafia. Katya's descent into the dark world of the high-stakes casino trade is a nightmare of cruelty, torture, and death, but she can't stop now. The girls in the trafficking trade need her to do what she does best: take a gamble.
