Last week, a blog by 12-year-old Norwegian girl Thea went viral. Thea blogged about her feelings surrounding her upcoming wedding to a 37-year-old man named Geir.

Later, it was revealed that Thea doesn’t exist. Her blog and story were created by international aid organization Plan to draw attention to child marriage. It worked, as the blog went viral.

Child marriage, defined as marriage before the age of 18, is still a large issue in developing countries. Here are some relevant stats, found from UNICEF:

Ratio of women ages 20-24 worldwide who are child brides: 1 in 3
