Possibly lost in the tragic news of the summer was story of two women stoned to death in two days by ISIS in Syria. Working on my series, The Perfect Stone, a few years ago I was struck not only by the horror of the penalty—what does it mean that in the 21st century there are still women being stoned to death—but by the question of what would be necessary to cary out the sentence: a pit would need to be dug, many volunteers would be needed to throw stones, and the right size stones would need to be decided on. This last item,  though chilling, made me think—what is the perfect stone for killing a woman?

I hope the video below, and the visual essay, can serve as a proper memorial to women targeted for honor killings in the 21st century.
