Killers are killed in the manner they killed. While it has some commonalities with Freesia (sanctioned criminal justice killings), but this takes a different approach and while the crimes are heart-rending, it's not as dark as Freesia. The quirky set of specially skilled, highly-empathetic, eccentric, revenge-executioners are an interesting and likable lot. A very good read. Hope it keeps updating.
