Death Dealer - Mark Rogers - Bog

Billionaire Joe Sinclair is bored. To him, life is one big "been there, done that."
However, there is one thrill Joe has yet to experience and he's willing to pay any amount to make it happen: Joe wants to know what it's like to kill a man.
Courtesy of his illicit connections, Joe hires Haden, a mysterious ex-mercenary to take him and his three best friends on the kind of African safari you won't read about in travel brochures. But when the bullets start to fly, Joe and company find themselves on the absolute wrong side of the predator vs. prey equation.
