A twisty story that kept me questioning who was the craziest for the first 100 pages. Poor Isabelle is trying to finally assert some independence at college, but she has an overbearing mother and a psychiatrist that is probably crazier than her patients. 
This read did start off a little slow for me but it picked up and took me on a great ride. A little less than half way through it picks up pace and sets a dramatic scene. The chapters are separated into Isabelles view, Stella's view, and Kerstin's view. Though different views, it is written in first person. I had to make sure I looked at each title heading to switch perspectives properly. I may have liked it even more if in 3rd person.
