The girl who saved the king of Sweden / Jonas Jonasson

Summary

"In a tiny shack in the largest township in South Africa, Nombeko Mayeki is born. Put to work at five years old and orphaned at ten, she quickly learns that the world expects nothing more from her than to die young, be it from drugs, alcohol, or just plain despair. But Nombeko has grander plans. She learns to read and write, and at just fifteen, using her cunning and fearlessness, she makes it out of Soweto with millions of smuggled diamonds in her possession. Then things take a turn for the worse... Nombeko ends up the prisoner of an incompetent engineer in a research facility working on South Africa's secret nuclear arsenal. Yet the unstoppable Nombeko pulls off a daring escape to Sweden, where she meets twins named Holger One and Holger Two, who are carrying out a mission to bring down the Swedish monarchy...by any means necessary.
