I only read The story of son, it was great. I really enjoyed it. It was short but really got me I would have liked to read more about Claire and Michael and hows and whys.
It definitely doesn't happen in BDB world (no transition, feed once a year, ...)but it happens in Caldwell.
It seemed to me that Michael was the basic for creating V, Z and Mhurder. They share some simillarities but probably I'm mistaken as the publish date is 3 years after dark lover.
