Dirty Secrets is one of the best support books yet put out. It takes the general city-based scope of most Vampire Campaigns and shoots it out of the water: providing an ancient, world-spanning conspiracy that Storytellers can use to torment their players for years in the future. I'd advise against it if you like to run a smaller-scale set of stories, True Hand Characters are generally much older and more powerful than V:tm characters. that would be my only significant criticism that the Templates in the back are a bit "overstocked" -- there are way too many 7th & 8th gen templates, almost none of 9/10, making the characters in the back suitable more for "deus ex machina" characters and "evil nemeses", rather than standards for PCs.
