The First Horseman — Clem Chambers

This next installment in the Jim Evans thriller series focuses on what might happen if people had the ability to turn the human body clock back

If we were able to repair telomeres, the tiny proteins found at the end of every strand of human DNA, we could live much longer, perhaps even become immortal, like Hydra. Yet when such a medicine would result in many more billions of people fighting to live among ruins of an ecologically exhausted planet, what would be the point? Professor Cardini sees no point. He plans to deal with seething humanity in a way that will both shock and horrify. Will he succeed in releasing his tiny, but deadly "First Horseman" and wreak bloody havoc on the world? Not if Jim Evans can help it.
