A secret US government agency, CROM, fights terrorism by apprehending or terminating post-Soviet scientists before they sell the technology of mass destruction to terrorists. A rookie CROM agent, Marianna Bonaventure, and a brilliant consultant, Jonathan Knox, find themselves on an undercover mission to locate a missing Russian physicist. Instead, they discover a secret far scarier than terrorists with nuclear weapons.

The famous "meteor" that devastated Siberia's Tunguska wasteland in 1908 was no meteor. It was a microscopic black hole that entered the earth's crust--and never exited. Trapped, it may eventually devour the earth. But a small, clandestine group has developed secret technology to capture the black hole. If the conspirators succeed, the world will be enslaved by a dictatorship made omnipotent by the black hole's quantum effects. If the conspirators fail, they will accelerate the black hole's destructiveness--and guarantee the earth's immediate annihilation. Bonaventure and Knox rush to stop the conspirators--but they may already be too late. --Cynthia Ward
