When Rhett intercepts a stranger, Shelley in his holiday home it becomes apparent that she is not just an intruder caught in the act of illegally trespassing.
Rhett and Shelley travel through a space-time portal where they are met by Dee, their twelve-year old daughter that they never knew existed. Dee is desperate for her brother, Corwin to be rescued. He has been caught in a trap set by the girifa, the reptilian equivalent of humanity. In this world, humans are the aliens.
As they continue their journey they befriend fellow travellers who help them in a seemingly haphazard quest. However, their lives appear to have been predetermined with a destiny that will affect not only present day Earth but also the future.
Evil forces are also out there with sinister objectives of their own. Rhett and Shelley learn that the enemy are not the girifa but humans living a parallel world from their ancestors' time.
But who is really in control? Journey through the time portal where time, space and parallel worlds intertwine with an ultimate disaster that only Rhett and Shelley can halt.
