Nathan Morrell is one of the foremost designers of thrill rides, and for him the occupation is much more than just a career; it's an undeniable passion. Today is a proud day indeed. The inaugural circuit of Nathan's latest creation, the world's newest and most thrilling roller-coaster, is an event that has been long-awaited. The anticipation of the very first ride of the Black Mamba has created a buzz in the state of Virginia - for politicians, the public, the favoured first riders, and for Nathan's company, Flying machines Inc. But this event is also being watched with interest by others-people lurking in the shadows who see the Black mamba as a means to an end. There is a spine-tingling truth at stake that involves much more than just a mere ride at an amusement park. A truth that is intended to remain secret.
