[@WeepingLiberty] The first five books are really good, story kinda lost me after that. But the Brotherhood are hot and spicy and I love them. Rhage and Zadist (second and third books) are my favs. 

Be prepared though, the books are not child-friendly for several reasons. If you don't mind sex scenes, graphic gore description and drug abuse/reference then check them out.

Brotherhood List:
Wrath
Rhage
Zadist
Phury
Tohrment
Vishous

Others get added later (not spoiling) but those are the main six.
