Horror in the Trenches

Publisher's blurb:

As I woke up, I held my head in my hands.
I don't know why, but since we've been working on this case, the nightmares have become more and more frequent. I keep thinking about the constant fighting, the lost friends, the permanent fear that freezes your blood, more than the coldest winter ever will.
Last night I was still crawling in the mud, bullets whistling over my head, hunger tugging at me.
This night again and like the previous ones, I relived the horror of the trenches!
