Master Over You is definitely a dark dark romance. Obviously the male protagonist is psychotic, but I just couldn't continue reading.
The style wasn't very clear to me or easy reading. The characters didn't draw me in either, Chastity was a 21 year old, but was portrayed as a young teenager the way she talked and carried on at the start.
I do not like doing a DNF post and I am sorry. This may suit other readers, but isn't for me.
