First, I liked the fact that the history of the Tremere was laid out nicely. However, this book fails to mention the struggle between Tremere and Salout for the control of Tremere's body. It also fails to mention WHY the Tremere Antitribu were destroyed. I may be wrong, but I think that is part of the history of Clan Tremere.
Still, I liked to see how well organized Clan Tremere is. It's obvious why their enemies fear them, as the most powerful and cunning Tremere are the ones in charge. Also, I thought that the various rituals presented in this book were interesting, especially the one that helped other vampires to learn Thaumaturgy. However, I bought this assuming that I would get a better understanding of the discipline of Thaumaturgy, which I did to a point, but not as much as I would have liked. For instance, what seperates Tremere blood magic from, say, Assamite or Setite Sorcery? Also, I would have liked a clarification of how exactly you advance your Thaumaturgy rating as opposed to the various paths that you have. Vampire: The Masquerade rulebook attempted to explain it, but I still avoid creating Tremere characters simply because I'm not sure how to advance in their most important discipline.
Also, on the outside binding of the book, there is always the "clan symbol" that goes along with the given clan. I was surprised to see, for this book, a rose! If you're familiar with Vampire: The Masquerade at all, you'll realize that the rose is the symbol for Clan Toreador, not Clan Tremere! Obviously, this isn't a big thing, but I still thought I'd bring it up. To me, it just takes away from the overall presentation of the book; since basically I buy some of the books just to say I have them. I like having the various clanbooks all next to each other, but then when you see one that has a flaw like that (especially on the outside!) it takes away from the, again, presentation.
Overall though, it explains a lot about Clan Tremere and it's inner workings, which is probably what most people expect from this book. So therefore, if you're looking for that, you will be pleased. If you want a sprawling history of this clan, however, you should look elsewhere.
