A troubled teenager becomes engrossed in an internet forum whose members have strange proclivities. An online moderator faces the wrath of a vengeful predator. Two boys meet on a park bench, and one of them is hiding something under his sleeve. These nine stories plumb the depths of self-harm in the internet age and beyond. They dredge up the dark parts of the human psyche and offer a picture of pain and depravity, painted in viscera-red. They are in turns brutal, shocking, beautiful and startlingly relevant. Make no mistake, though: this book may hurt you.
