Visioner

Peter, 17 years old, six foot tall and good looking has started to notice a ghostly orb hanging around in his bedroom, at the home he shares with his divorced mum.
He resolves to speak to it the next time it appears and just as he is about to fall asleep that evening, the orb appears. He speaks to it and it answers back. The orb turns out to be nothing to do with a spirit but is actually a contact device called a 'Visioner' belonging to an alien ambassador, who has been studying and learning about Peter and his girlfriend Julie for nearly four years.
Having decided that Peter was now old enough to understand the situation and mature enough to deal with it, the alien has made contact. After meeting the alien, whom Peter nicknames 'Clix', their friendship begins.
Peter mentions to Clix that he's seen another Visioner, a blue orb, which Clix warns belongs to a rogue alien race, on the lookout for suitable gene donors, to strengthen their weakening race. Clix warns that it might affect Julie and allows Peter to let Julie into the secrets of the Visioner.
The very evening that she discovers everything, Julie's younger sister Jeanie is abducted along with her best friend Li-Wei.
Through the use of the Visioner, Peter discovers that they, along with numerous other young girls are being held in a hypnotised state inside the rogue alien spacecraft, awaiting the gene harvesting process.
So unfolds the race to find and free them before their bodies are violated and possible further harm occurs.
