It's the 12-page letter that's reverberating around the world.
If you have a social media account you're unlikely to have missed it during the past few days, such as been the reaction.
The harrowing and intensely moving letter was written by "Emily Doe", a 23-year-old sexually assaulted by a then-Stanford University student as she lay unconscious after drinking too much at a party last year.
Last week she stood in a courtroom and read the letter to her assailant Brock Turner, who was sentenced to six months in prison. A sentence that in itself would cause outrage.
But had it not been for the power of the internet making her letter go viral, the outrage would probably have been contained to California.
