I made it home. But something came with me ...From hero to outcast. From saviour to biohazard ...As hollow victories go, this one is hard to beat.When Driver and I saved Earth from the Anomaly's suffocating radiation, we thought it was all over.Our triumphant return from the occupied alien world of Bayzen was supposed to draw a line under everything.The problem is, we didn't come home alone.No one has ever seen anything like this.What they're calling it sends shivers down my spine: a parasitic alien pathogen.It could be a virus, a toxin, or maybe something even worse. And believe me: what we don't know definitely can hurt us.It's too late for me-I've been exposed. But this has never been about me.It's going to take some incredible risks and another long-shot space mission to get to the bottom of this, but I'll fight until my last breath to undo the damage I've done.As a horrible question echoes in my mind, I'll do anything to make sure the answer is the right one:Am I Earth's last hope ... or the man who sealed its fate?
