Cornerstone by Vendelin

Cornerstone - Vendelin

4.5 stars. This is a thoughtful fanfic written in the present tense by Vendelin. Mostly a curtain fic with Stiles and Derek going about their everyday lives in Beacon Hills, there are no supernatural creatures in this AU. Stiles has been blinded and Derek is a Marine veteran with PTSD. Stiles manages to draw Derek out of his isolation. Some hot sex scenes and excellent artwork.

description
'After his last tour, there was no hope of him ever returning to who he used to be. Another soldier once described it as being too trapped in a war to be at peace, and too damaged to be at war. Derek doesn't think anyone has ever expressed it more perfectly.'
