The blood control trick has been an interesting one to play with. There is a scene in this book that I wrote one way, then changed completely as time went on. Maybe I’ll discuss the scene after the books are all published. Spoilers aren’t that much fun.
From Protector of the Grey House:
Anthony had researched Edwin’s nightly ritual of giving his people his blood. Edwin would feed humans and vampires his blood every night. With humans, it almost always seemed to negate their will power. With vampires, it depended on their age. Anthony and Joseph seemed to think it had more to do with the person drinking the blood then the blood but were still unsure how it worked. Some who drank Edwin’s blood were affected in a similar manner as Natalia. The mayor of San Francisco drank Edwin’s blood and was very much under the Captain’s control. Joseph nodded to himself. Natalia would do anything Vincent wanted because she was under his control.
