I loved this book full of unlikeable characters & unreliable narrators. Dr. Caroline treats a new patient who leaves halfway through their first session after professing he‘s going to commit a murder. Before he parts, he tells her he knows who she really is. Thus begins this twisty novel told from 3 POVs: Dr. Caroline & 2 other people connected to her. I fear to say much more as I loved going into this novel blind & trying to figure out the truth.
