Martin Wise dreams of travel in the 4th Dimension. His 'lucky' stone helps him fulfil that dream. But his stone is not the only one. Others exist. Some stones fulfil their owner's dreams while others create their nightmares; time travel has consequences. For those in power, manipulating time represents the chance to change the past. With the world descending into anarchy, the testing of a neutron probe using Thor's Hammer and a covert mission into enemy territory reveals the existence of a parallel, time-star universe linked to our own. That revelation sees the Scientists' and Politicians' worlds collide.
