In this Sept. 28, 2010 photo, Liu Xia, wife of Chinese dissident Liu Xiaobo, speaks during an interview in Beijing. When the police came for Liu Xiaobo one night nearly two years ago, they didn't tell the dissident-author the reason for taking him away. The line in the detention order for "motive" was blank. But everyone in Liu's dark Beijing apartment knew exactly why. Liu was hours from releasing a call for peaceful political reform in China that would represent the democracy movement's most comprehensive demand ever - and that earned Liu multiple nominations for this year's Nobel Peace Prize.

The 25-year-old Zeng said she wanted to keep speaking out on human rights, but felt deep fear due to intimidation of her and her jailed husband Hu Jia.
