Mastermind Part 4. Cartier's War For The Throne (en Inglés) - Joy Deja King

Cartier Richardson thought the war was over. With Lila behind bars, Callie's empire in ashes, and the woman he loves wearing his ring, the throne he built from nothing finally felt secure. Then an unmarked envelope arrives containing a photograph from a past he buried thirty years ago, and everything changes. Solomon Richardson, international power broker, ghost, and Cartier's own father, has stepped out of the shadows. And he hasn't come alone.

Solomon has been watching his son's ascent for decades, protecting him from threats he never knew existed, positioning himself for the moment when CR Enterprises would be powerful enough to absorb into something much larger. Now that moment has arrived. Callie Morgan is trapped inside Solomon's operation and playing the most dangerous game of her life.  Gavion Richardson, Cartier's long lost older brother, is caught between his father's empire and a loyalty he never expected to feel again.

The throne is under siege. The secrets are about to surface. And Cartier Richardson is about to discover that the most dangerous enemy he has ever faced shares his blood. Mastermind 4: Cartier's War For The Throne is the most explosive installment
