Gravity of the Divine by Chris Hart

Trent is a man measured by his enemies and Trent has collected more than most. A trained combat agent he is disillusioned by the World Gov leaders. They seem more interested in enriching their own lives than repairing the damage done to the planet. So he decides to create a sanctuary of the old Moonbase complex. Built by the military, sold to the American gangs to create a playground for the rich. Abandoned since the war began 2 centuries past. He needed all the resources he could get to achieve his plan making deals with everyone; promising them what they wanted to hear, a safe life. Now the time has come to pay back his creditors, The Asian Tongs, the Russian mafia, the American gangsters and the ruling African Warlord. Under increased scrutiny from the World Gov., Trent has reached the point where he has to win the future or lose everything. Unknown to all, a more insidious group waits in the shadows, wanting Trent's prize for themselves.
