1st has to be Z, with Lover Awakened, best book ever !!
2nd Butch with Lover revealed and then comes Rhage in third followed by Wrath and last V ! I have to say I think the reason I thought Lover Unbound lacked substance was because JRWard seemed to rush his relationship with Jane and it seemed over before it started. But it was still a great book and I loved John and his pals !!
