Today marks two years since Boko Haram militants stormed a girls’ school in Northern Nigeria and kidnapped more than 100 girls, among them Christian teenager Leah Sharibu. Five of the abducted girls died and the others were released through back-channel efforts, but Leah remains in captivity, held by a terrorist group that oscillates between threatening to kill her and vowing to keep her as a “slave for life.” It’s the price she pays for refusing to renounce her Christian faith.
