Chronosphere: A science fiction novel

In a remote colony on Mars, physicists have used a particle accelerator to artificially create miniature black holes. By accident, two black holes orbiting each other with relativistic spins have opened up a portal to another universe. Engineers Masamune Hughes and Tom Hildebrandt build bigger and better machines to enable them to peek inside, and even cross the threshold themselves. What they find defies all description.

Meanwhile, a mysterious x-ray storm is slowly creeping across the planet destroying everything in its path. Scientists are mystified because the x-rays barely amount to what one might expect to find in a dentist's office.

When whole communities turn up deserted and scientists are found murdered, Tom and Masamune realize there is something deeper going on than anyone realized. It becomes a race with time to solve the mystery and figure out how to use the portal technology to save the planet from a worldwide catastrophe.
