Bunker by Andrea Maria Schenkel
It had been a normal day at work. Monika was locking up, ready to head home, when the man arrived. She didn't see his fist until it was far too late. Bundled into a car, tied up and taken in darkness to an old mill in the thick of a forest, she has been flung into a bunker. It is only now, as time passes and she sees her attacker in the light, that she notices the startling resemblance to someone from her very dark and buried past. Someone she never wanted to see again.
