People Who Eat Darkness

Fascinating and heartbreaking. (Though content warnings: for sexual assault, particularly by use of GHB/Rohypnol; murder/abduction - the descriptions aren't graphic overall but it's a big part of the story, unfortunately, so be advised.) The author is a longtime foreign correspondent for the British press, and seems to do a good job telling the story without turning it into “look at those strange foreigners” gawking or exploitation.
