Black Venom

Wade Ross, raised as an aboriginal in the deserts of Australia, went on to become one of the most dangerous and efficient Special Forces dark cover operatives.

While on a mission to uncover and destroy a suspected gun running/manufacturing syndicate he learns his mother and sister have been murdered by those he is chasing.

Things are now very personal and somebody will pay.
He zigzags through three continents, both by himself and with his team of multi-national ex-Special Forces companions, destroying all he comes in contact with but all the while aware somebody very high up is after him.
