Leaving L.A.'s Parker Centre, Shane Scully and his wife, Alexa, agree to meet at home in one hour. Shane gets there; Alexa doesn't. In the middle of the night, he's called to a crime scene on Mulholland Drive: the African-American victim who appears to be a Crip gang banger, has been executed in gangland style. Shockingly, the body is in Alexa's car and her gun is found near by. But Alexa is missing. Shane's frantic investigation into his wife's disappearance soon takes him inside a bitter and violent feud between two rival hip-hop record companies. At the centre of this war is one of the most lethal adversaries he's ever encountered: Stacy Maluga, a trashy, beautiful Lady Macbeth-like, white woman raised in Compton, married to a multi-millionaire rap mogul and known in the gangsta hip-hop world as the White Sister. Shane is no stranger to big trouble, but this time he's met his match in a powerful and media-savvy enemy who will stop at nothing to forge her own hip-hop empire.
