Harry is a member and “de facto” leader of a tightly-knit group of four security operatives with military backgrounds.
At the time of the outbreak of the Crossed virus, his team worked as security for UK Prime Minister Gordon Brown. In that capacity he learns of the situation from a fairly privileged standpoint.
Five years later he is still with his group, all of which have survived that far and have been seeking other groups of survivors. They have a bold plan regarding the situation of the Crossed in the UK.
