I also liked the blurb:
An underground female mafia rights the wrongs of an unjust society in this gripping story of everyday women taking matters into their own hands where the justice system has failed. For many years they have worked quietly and gone unnoticed by the world in which they live, until one of them goes missing. The wrong people start asking questions and before they know it, they are in danger of being exposed. How will they save one of their own without putting their organization in danger? Will they be able to remain a secret?
I "bought" it.
Looking it up here, I also found GreyWarden's review. Hmm...
