Vicious was among my favorites of 2016. It was smart and well-written, had characters that made sense within the story, and, the story unfolded in a way that made you extremely interested in what would happen next. 
 There are almost no 'good' people in this story, certainly not the main characters. They were both sociopaths, really, one, only slightly worse than the other. 
 *sigh* likable sociopaths. #teamvictor 
 Great story - smart read that I would totally read again, and recommend to anyone who likes stories with really fucked up characters, excitement, weird plot elements, and, is nearly unlike anything you've probably read before.
