Diamond Coast: A Milo deCogan Thriller (Book One of the Relief Solutions Series)

By Robert Cole

When a humanitarian compound in South Sudan is overrun by armed rebels, Caitlin Bishop-a young aid worker and the daughter of the U.S. Secretary of State-vanishes without a trace. With official channels paralyzed by politics and deniability, her father turns to the only man he trusts to operate beyond them: Milo deCogan.
A former special operations officer, Milo now leads Relief Solutions, a private rescue firm with a singular mission-to protect those who protect others. His team deploys into the world's most dangerous regions to recover humanitarian workers, aid staff, and civilians abandoned by bureaucracy and forgotten by governments. Relief Solutions isn't about contracts or influence. It's about bringing people home.
The assignment looks straightforward: locate Caitlin before her captors disappear into the lawless frontiers of Central Africa. But as Milo tracks her across borders, he enters a brutal shadow world where corruption, resource exploitation, and human suffering are tightly intertwined. From shattered refugee camps in South Sudan to smuggler routes in the Congo and the windswept outposts of South Africa's Diamond Coast, every step forward tightens the clock-and raises the stakes.
Milo isn't the only one hunting Caitlin. Jimmy Liu, a ruthless Chinese intelligence asset working for a powerful mining magnate, will do anything to keep his employers' secrets buried-even if it means killing her. What begins as a rescue mission becomes a race against global forces determined to erase the truth. As Milo closes in, he discovers Caitlin's kidnapping was never random, but tied to a massacre and a secret powerful enough to ignite international consequences.
Fast-paced, cinematic, and grounded in real-world geopolitics, Diamond Coast is a high-intensity thriller about courage, loyalty, and the cost of doing the right thing when no one is watching. It launches the Relief Solutions series with a mission that was never supposed to uncover the truth.
