An Alien Affair

Her name is Frell; six-foot tall, blonde and beautiful. His name is Scott; almost six-feet tall, broad shouldered, attractive, dark-haired and gymnastically fit.
She belongs to a secret off-world colony of humans, originating from abductees previously removed from planet Earth over many centuries and generations. He is an military airman, operating with the British Royal Air Force as a highly experienced aircraft technician and engineer.
Frell is the captain of a spacecraft, one that resembles the stereotypical flying-saucer often seen in Sci-Fi movies on Earth. There is one other on board and he is the pilot. His name is, Drang. They are to abduct Scott... again!
Scott has previously been abducted, where the union with Frell produced a daughter. She is presently living on a distant planet and destined to be one of the colony's leaders due to her exceptional DNA & extra-sensory intelligence. The colony now requires another with the same intellect and abilities. Scott is unaware he has been previously abducted by extraterrestrials, although he suspects there have been occurrences in his life that he cannot quite fathom or explain. A missing few hours or a day here and perhaps there with strange puncture marks appearing on his arms, and more. He never tells anyone his thoughts but keeps them to himself. He has no recollection of the love he's shared with Frell, a bond that is so strong when they are together it's almost unbreakable - but that could soon change!
There is another species that occupies space and one that is especially selfish and greedy, known as, Greys. They declare themselves to be the oldest and most original species of them all and space ultimately belongs to them. They would have laughed at the humans who landed on Earth's solitary moon, laying claim to it on behalf of Earth with that first step; but being quite emotionless they simply watched with blank expressions while recognising the human-virus was learning to move into space; a daunting prospect that concerns them greatly. They also abduct humans, on a regular basis, but for completely different purposes to the peaceful colony that Frell belongs to. The Greys show no respect or clemency to any, having their eyes set firmly on dominating Earth and making ready to lay their own claim to it.
After driving to the Isle of Skye on his ancient BSA motorcycle, he studies geology on a Scottish island's deserted coastline. Scott is once again taken by Frell, lifted at night while asleep in his tent on the edge of a supposedly haunted village. He will once again become acquainted with his forgotten lover, passionately taking her in his arms. She has missed his touch and loves him with all her heart and would prefer to take him back to her Mothership, eventually setting up home on their distant planet. But she is under strict instructions by a ruling council to safely return him to Earth, leaving no knowledge of their meeting. It breaks her heart to leave him... It always does.
The Greys want Scott for their own purpose, to complete a Grey/Human hybrid that will rule Earth following the eventual social breakdown of human domination. His genes are not only unique but are of great significance, whereupon he has become a must-have organism. His sought after DNA is to be the final piece in their hybrid jigsaw.
Frell and Scott are themselves abducted, where they must escape to fight a life threatening foe alongside their pilot. They must do battle with a ferocious adversary, not only to save themselves from being torn apart for their organs, but also for the future of the entire human species .
The final battle takes place above Earth. There can be only one winner!
