Many scientific studies suggest this could be true. 
It is rumoured Governments secretly monitor those with a certain blood group. 
The question is: WHY?

Mankind harboured a deadly secret. Scientists had suspected certain blood types must be of alien origin. And they were right!
Richie was looking forward to a weekend away in a country cottage. He had received a blood transfusion whilst recovering from a motorbike accident and needed to recover.
This was going to be the start of a terrifying journey into the unknown, threatening the very essence of his life.
