Lagos, Nigeria — In a plush living room of a home in a wealthy suburb of Lagos, three teenagers are huddled around a computer.
Kudirat Abiola, 15, Temitayo Asuni, 15 and Susan Ubogu, 16, want to change the law on child marriage in Nigeria and they're deep in discussion, even ignoring calls to break for a hearty Sunday lunch of jollof rice and southern fried chicken.
More than a third of girls in Nigeria end up in child marriages, and with 22 million married before the age of 18, the nation has among the highest number of child brides in Africa, according to a 2018 UNICEF report.
The girls are checking an online petition they've started. They know it's a tall order to get lawmakers to close the legal loopholes that currently enable men to enter marriages with girls under 18. But they are unfazed by things others their age might be.

Abiola, who aspires to be a children's rights activist, says it's a very emotional issue for the three of them."How do you give a young girl such a responsibility and have her education, friends, and family taken away from her?" she asks.
Campaigning for human rights is second nature to Abiola, who comes from a family of prominent activists.
    Abiola's grandmother, also called Kudirat, fought for Nigeria's democracy before she was assassinated in 1996. It came three years after the military jailed Moshood Kola Abiola, the apparent victor of the annulled 1993 presidential elections and the teenage activist's grandfather.
    Abiola is also inspired by her aunt, Hafsat Abiola, a prominent civil rights activist.
    "Those are my role models," the 15-year-old says. "They have broken the stereotype that girls cannot achieve what boys can."
