The Unintended Heiress

This dual timeline saga is based on the scandalous lives of Belgium's brutal King Leopold II, his young mistress, her longtime lover, the King's three daughters, and the mystery of a vanishing fortune.
THEN
At his death in 1909, Leopold was believed to be the wealthiest man in the world. A fortune made from enslaving the people of the Congo to harvest ivory and rubber went to lining his pockets rather than filling his kingdom's coffers. He triggered the genocide of an estimated ten to fifteen million people to satisfy his greed.
NOW
Oceane's life is turned upside down when she joins her grandmother on the French Riviera during summer break. She is surprised to learn that her family owns a magnificent villa on Cap Ferrat (the peninsula of billionaires) that has been unused for decades and nearly untouched for over a century. Gran is forced to prepare Oceane for an advancing threat by telling her the unvarnished truth about her family and their connection to Leopold's lost fortune.
