Shame of Clones - Karma Inc Files, #3

The witches promised Barney a body, and it's time to pay up. When they fail to live up to their end of the bargain, he heads out on his own in search of a witch who can make his dreams come true. After all, an imp can only be so patient. But his timing couldn't have been worse. The world of magic has inexplicably gone haywire, and it leaves the witches of Karma, Inc. scrambling to get their magic back on track.
Trouble is compounded by an infestation of clones, and the witches each find themselves in a romantic crisis. Evil spirits, smugglers, and thieves abound as these magical misfits struggle to save witchcraft, Barney, and their love lives.
