Sin has been obsessed with Ellie for 
years and already claims her as his.  But she is promised to another.

This book is very dark and incredibly unhinged, so check the TW before starting (it's a long list).

Ellie has been through hell and back. She is convinced that she deserves all the bad things that happen to her and eventually just accepts that this is her lot in life. I really wanted to see her get her revenge and in a round about what she does, but I wanted her to be the one to light the match. She has been groomed by most of the men in her life and is SA a lot... Even by Sin who apparently "loves" her. (It's not CNC, it's R@pe). It honestly feels like Sin is just continuing her grooming- he never using a safe word, ignores her pain, tries to control her, r@pes, and just keeps damaging this poor girl. 

Sin believes Ellie is his, yet he can never quite keep her safe. With all the cameras and stalking, you think he would be able to protect her better. He is the typical sadistic, obsessive, possessive, and unhinged MC with the personality of a wet blanket. Frankly, he is not likable or redeeming at all. 

Tropes: stalker, dark, college, forbidden, secret society
