Black Dagger Brotherhood/YMMV

Crowning Moment of Sadness: Wellsie, her unborn son, and her cousin, Sarelle, are slaughtered by the lesser Mr. O in Lover Awakened.
- Jane being murdered in Lover Unleashed and Vishous's desperate flight to save her was this Up to Eleven for some readers.
  - When it seemed like Xhex was going to die as Lash's prisoner after the Brotherhood had found where she was being held but had no idea she was still there thanks to a barrier which trapped her in a Pocket Dimension as if she was a ghost.
