When she is eleven years old, Martine's parents die in a tragic house fire. She is sent to live with her grandmother on a game reserve in South Africa. Martine has never met her grandmother, in fact, she didn't even know that her grandmother was still alive. Her parents had never mentioned her. And her grandmother doesn't seem at all happy to meet Martine. Still worse, there seem to be a lot of secrets at Sawubona, and nobody is prepared to tell Martine the truth. Struggling with loneliness and grief, Martine's only comfort is a white giraffe. This rarest of creatures seems to feel an affinity for the lonely little girl and she for it. The white giraffe is regarded on the reserve as nothing more than a fable, but Martine knows he is real. She has ridden him. But the reserve is threatened by poachers. The white giraffe is in danger and Martine is the only one who can keep him safe.
