Forty Acres by Dwayne Alexander Smith

Martin Grey, a smart, talented  lawyer working out of a storefront in Queens, becomes friendly with a group of some of the most powerful, wealthy, and esteemed black men in America. They invite him for a weekend away from it all—no wives, no cell phones, no talk of business. He discovers a disturbing secret that challenges some of his deepest convictions.

Martin finds out that his new friends are part of a secret society dedicated to the preservation of the institution of slavery—but this time around, the black men are called “Master.” Joining them seems to guarantee a future without limits; rebuking them almost certainly guarantees his death. Trapped inside a picture-perfect, make-believe world, Martin must find a way out that will allow him to stay alive without becoming the very thing he hates.
