4.5 stars. This book is INTENSE, and is basically 1 big trigger warning. It starts with the transcript of a court case. Then a chapter of happy Cathy in 2003, then a chapter of fully wrecked Cathy in 2007. You *know* something awful happened to her, and the anxiety of when it is going to happen, then the impact on the current story lines... Brilliantly written, but not for the faint of heart. Readers beware, but if you can handle it, a really great story.
