Children of the Blood is a great resource, and exactly the sort of content that I enjoy. The range of characters on offer can be easily dropped into any story, and they're loaded with hooks, and plot elements that you can draw on and bounce off your players. It not only advances the setting and adds in great hints at what else lurks out there, but importanly shows how religion, faith and the cult structure works in universe. Not every adherent is fully dedicated, and each of them come at it from thier own angles - everyone has their own questions to answer and reason to do it.
Overall, i love this book, and it works very well for me. On top of the top quality writing, the book looks amazing as well, and the art style is really evocative of the setup. Whether your an ST that wants to have some pre made story hooks, a player that wants to see some great examples of how cultists can be displayed, or just a person who loves the lore of VtM, this book is well worth picking up.
