4.5 stars.

I love writers who can make a bad character feel good. Ruby is definitely not the best person, but somehow she still remains likable. And placing the murderess as a therapist? Love that. While some of her actions are undeniably beyond sane, the way she is presented nearly makes the reader feel that her choices are justified. It's an odd juxtaposition. Unsettling and yet at the same time oh so gripping.

The book is dark and yet super intriguing. The writing is nearly effortless feeling and the plot moves pretty comfortably. Ruby is really well developed as a protagonist and the claustrophobic construction of the narration (focusing super narrowly on Ruby and her actions) feels natural.

A really good mystery thriller debut. It created so many conflicting feelings in me and I loved it for that.
