Project Pendulum is the first practical experiment with time travel. As time mechanics requires that the two travellers' masses be precisely matched, the first travellers are a pair of identical twins. For paleontologist Sean Gabrielson the chance to journey back to the age of donosaurs was worth any risk. For his physicist prother, Eric, the chance to see ninety-five million years in the future was equally irrestisible. What enither planned on, however, was how the inhabitants of those times would react to their presence. But, once their ride through time begins, there is no way for either to leave the experiment un til they reach Time Ultimate, the outer limits of Pendulum's reach.
