Codas and Calibers - The Codi Cassidy Mystery Series, #3

It was supposed to be just another gig for Codi Cassidy, a country music star. A wealthy businessman hires Codi Cassidy and her band to play at his private costume party for him and his guests. During the show, a violent storm rolls through, the lights go out, and someone drops dead. When the town's police chief, who is also a party guest, gets incapacitated, and with no outside chance for help, it's up to Codi to work through the guest list to determine whodunit.  It's music, murder, and mayhem in this third book of the Codi Cassidy Cozy Mystery series.
