Dapchi, Nigeria (CNN)Under normal circumstances, Leah Sharibu would have shared a special birthday meal with her family under the bamboo covering protecting them from the Sahara desert dust swirling around them at their home in northeast Nigeria.

At some point during the celebration, they would have bowed their heads in prayer, asking God to bless Leah on her birthday and to make her dreams come true.
But this birthday, her 15th, was different and her family spent the day crying and fervently praying. They don't know where she is.
Leah was one of the 110 schoolgirls kidnapped by members of the terrorist group Boko Haram in February from their school in Dapchi, in northeast Nigeria.
    All the other kidnapped schoolgirls from Dapchi have been freed -- except Leah who her friends say refused to renounce her Christian faith to Boko Haram.

    Kidnapping of schoolgirls

    Boko Haram has become notorious for kidnapping young men and women during their nine-year insurgency in northeast Nigeria.
    The terror group has kidnapped more than 1,000 children in the country, famously kidnapping nearly 300 Chibok schoolgirls four years ago.
    More than 100 of the Chibok girls remain in captivity.
    Thousands of parents whose children have been taken by Boko Haram never see their children again.
