Book of my choice was "Sarah's Key" by Tatiana de Rosnay. I don't want to spoil it for those that did not read it yet, and they may, but book starts in Paris, in July of 1942. I gave you enough clues about book on my nails to grasp the concept of it.
Gray base is Joe Fresh - Fog. On my ring finger I have OPI - My vampire is buff and I stamped key using UberChic 1-03 plate, just because I did not trust my freehand. Rest is done freehand with acrylic colors.
