The Other Skin

Andreas, a guy who signed up for a project is taken to a new dimension.He's part of a Winter Colony and he has to train to get on this market, where he has to change human beings into 'other skins'. The only thing he has to do is change the direction of the humans blood flow. The human will have grey eyes and a skin as cold as ice.
After a couple of markets he changes this beautiful girl named Genevieve, who is member of the Summer Colony.
Everything is ok until there are deaths including their best friends...
Will they accomplish the training sessions or will they die as well?
