Dr Jemma Anderson is a respected Australian scientist. The idea of alien visitation, UFOs and time travel have always been, to her, a fanciful myth. But, as she hurtles through time and space in a massive spaceship, she is forced to re-evaluate. She had no idea she was born on the planet Anders Major but, rejected by Earth and unable to return to the war-torn Anders, she gratefully accepts the protection of the Inter-Planetary League. Arriving on Earth in the year 2099, she is shocked at the devastation caused by decades of war and sets about to help with the re-establishment, only to find that her mortal enemy Fredrick Pritchard has somehow followed and has formed an alliance with unfriendly aliens from the planet Ailazant. Pritchard and the Zants abduct Jemma's husband, Sean Bellamy. With IPL help, she travels across the universe to rescue him, but when their spaceship is stolen, they are stranded on the planet Condona, millions of light years from Earth.
