The Devil's Breath — David Gilman

WHEN AN ASSASSIN bursts from the shadows to try to kill him on the dark, windswept grounds of his boarding school in England, Max Gordon realizes his life is about to change forever.

After learning that his explorer father is missing, Max is determined to find him, no matter what dangers may lay in his path. A secret clue his father left behind leads Max to the inhospitable wilderness of Namibia, where he soon discovers a potentially massive ecological disaster masterminded by Shaka Chang, a very powerful and completely ruthless man--a man Max fears may have put his father in mortal danger. Max needs all the help he can get. Because whoever is behind his father's disappearance is determined to get rid of Max, too. For good.
