This is one of the best scenarios I have ever read. Be warned though... it goes to some very dark places and may not be for all groups. That being said, the material is handled with sensitivity and grace and the plot will definitely give a group memorable RP moments. No exaggeration... this easily ranks up there with the best like CoC's "Masks of Nyarlathotep", Warhammer's "Enemy Within" Campaign, and D&D's "Ravenloft." It is obviously very different in tone than those, but the care, scale, and potential for an unforgettable experience makes it an instant classic.
