Tanganyika, 1956. As revolution brews across East Africa, geotechnical engineer Alex Trevenen is dragged into a deadly Brotherhood conspiracy. It began as sabotage at the diamond mine he manages. Then his plane is tampered with. When his motorbike is run off the road, Alex wonders who’s behind the incidents and if he’s the target.

Then Megan Harrington, the South African ecologist he’s loved in silence for nine years, arrives in Dar es Salaam. Brilliant. Determined. Her search for the owner of a long‑lost Arab journal puts her directly in the crosshairs of extremists, pulling Alex into a fight that threatens not only their lives but the fragile, unspoken bond between them.

Head of Research at the University of Cape Town, Roger Morrison's research on the black rhino of Ngorongoro gives him the perfect cover to monitor the insurgency activities in the area. But the unexpected arrival in East Africa of his assistant, Megan Harrington, creates a huge problem. Not only for his cover but also due to her growing attraction to him.

A university-educated Maasai, Tumaini holds a fierce hatred for British colonial policies and land-grabbing ecologists. Recruited to the Muslim Brotherhood by a wealthy Yemeni, he will do anything to save the Maasai heritage from becoming extinct. His scheme to help the Maasai warriors regain their position and respect is aimed at exciting a revolution.
