Blood Stream (Book #1)

I am a scout in a war against a group of heavily armed rebels, who we name the 'Callers' and the war has lasted two years. In this time the enemy forces have dwindled and because the Central Command thinks we do not need the help, they give no reinforcements. One day, I get my wish of leaving the useless war but at the cost of leaving my one and only friend, although I had no choice I still regret leaving. Once I arrive at the new area, I am cast in a role I have no idea about and it's not only for a special mission. All I know is a dangerous beast has been let loose and we are doomed unless we beat back his rage.
