Life, above all - Allan Stratton

Like any girl, sixteen-year-old Chanda Kabelo has secrets. She is
determined to be loyal to her rebellious friend Esther, she worries
about passing her exams, and she wishes she didn't have to spend
so much time listening to her Mama chat with their nosy neighbour
Mrs Tafa. But one secret threatens to silence everything. All
around her people are dying, and everyone is afraid to say why.
But Chanda knows: it's because of AIDS. Chanda's Secrets is the
tense and deeply moving story of one girl's struggle to rescue the
people she loves from a tragedy that is destroying her world.
