The Chameleon: Previously Soul Mates by J. B.Anthony

Four multimillionaires end up homeless due to sabotage on their jobs, mental or emotional problems stemming from grief, or just plain racism. After almost being killed by gangs on the streets of New York or later California or coping with an antiquated culture of hatred in the South, they try to get help for their problems but the protagonist, Tiara (Tee'Ah'Rah) Wilson had a contract out on her life for something she does when she finally returned to South Carolina after fifteen years.
