The Black Diamond Trilogy — Brittani Williams

Diamond and Mica have been best friends since grade school, and have always watched each other's backs. After Mica moves out of their drug-infested neighborhood, they have a scandalous falling out and lose touch. It isn't until Diamond hooks up with one of North Philly's most notorious drug dealers that she's able to leave the place that she's always called home.

Under extreme circumstances, Mica and Diamond meet up and are back on the map as the Laverne and Shirley of the ghetto, but unfortunately, both friends have ulterior motives for rekindling their friendship. The two plot to get rid of the dealer and hit the road with his fortune, but one of them has her own sinister plan that could leave the other staring death in the eye.

Jealousy and greed create plenty of drama for Diamond. Even when she thinks she's on her way to a happily-ever-after ending, she finds herself fighting against foes she never saw coming. Will her “I rule the world” disposition keep her on top, or will Diamond lose the things she cares about the most?
