Time Storm — Philip R Benge

In the year 2494, time the last frontier had just been conquered, and the two most powerful megalomaniacs in the galaxy each want control of it. An out of work twenty first century researcher is caught up in a time storm, where he first battles against the universe itself to survive. Finally released from its clutches he must do battle against the jungle, a tribe of Troglodytes, an army of androids and finally an old evil, the Heliots. All the answers for our hero are to be found in the aftermath of the time storm upon the lonely planet of Orion.
