Book 1 (of 5): A duel between retro-punk rappers from the white-hot music scene in Las Vegas ends with one of them murdered. The problem for Gil Grissom and his team of crime scene investigators isn't a lack of suspects, it's too many--each with his or her own reason to want Busta Kapp dead. But when the suspects start becoming murder victims themselves, Grissom knows he's got to solve this case in a hurry - before the victim list goes off the charts!
