All the Lights We Cannot See

During this period, I am reading not one but two books at once. The short stories by Arthur C Clarke, and a newly realized novel called all the lights we cannot see. It is about two blind teenagers; A french girl called Marie-Laure and a German boy called Warren. So far, the book has described the life of the teenagers, why they went blind and the subtle beginnings of war preparations. I am on Chapter 12
