Singing and dancing as she performs in a school assembly, Younis looks for all the world like a typical Kenyan teenager, with a beaming smile and a grey and maroon uniform.
There's little outward clue to the trauma she's already been through in her 13 short years. When she was just nine years old, Younis's parents arranged for her to marry a man old enough to be her grandfather, in accordance with local Samburu tradition.
The Samburu are an ancient Kenyan tribe pastoralist cattle herders, said to be "distant cousins" of the Maasai. Even to outsiders, their languages and customs are strikingly similar.
