The book gives brand news informations about the True Black Hand, things that all good storyteller should know to make his chronicles even better. The concept of the sect in itself and his hiearchy are really great and it's a real pleasure to add it to current plots. However, as with some other supplements, White Wolf made really, really stupid mistakes; create new clans with non-vampiric disciplines that makes you cry or laugh, but not include them... A great book, but as always, the storyteller will have to take the best and let some stuff down.
