This month, Fatmata and Mariama Kabia, twin sisters who are senior international relations majors at the University of Pennsylvania, are seeing their entrepreneurial dream become a reality. The first issue of Memunatu, a magazine they have created for girls in Sierra Leone, will be distributed in middle schools and high schools in Freetown, the African country’s capital city, and Lunsar, the town where the Kabias' parents were born. The twins hope Memunatu will engage girls and encourage reading in a fun way.
