I See You/Clare Mackintosh/374 pgs.

Like most people, Zoe Walker takes the same route to work--in her case, a series of trains. Nothing is out of the ordinary until she sees a photo of herself in the advertising section of the newspaper. The contact information appears to lead to a dead end. When the police become involved, a pattern begins to emerge. This is a "read into the night" book--the reader has to know how it turns out. As in Mackintosh's I Let You Go, there are plot twists and turns. Highly recommended!
