Yin Tung Foo 
This is Business [EPUB ebook] 

Away from prying eyes, in hidden alleys and on invisible streets lies an underworld, privy only to those who know where to find it. A world built on trust, loyalty, blood and fueled by money and power. Foo Yin Tung has worked hard to get to where he is. He now oversees his gang’s online gambling and casinos and has a plan to expand its territory; a plan that will not only see him recognized by his chief, but also rid him of a rival gang. But blood begets blood and Yin Tung soon finds himself embroiled in the middle of a war-a war for territory, for pride, and to protect the ones he loves. Immerse yourself in this compelling, gritty and honest account of one man’s life in the underbelly of Singapore.
