This might just be my favorite in this series so far. The characters are embarrassingly real (except for one or two more vaguely drawn ones), and the premise is slightly less far-fetched than in the previous two books. 
 I also love how French inserts social commentary into her thrillers. A quote I dog-eared in this one, in which Frank is talking about raising his daughter in the post-truth era (before it was called the post-truth era): 
 "She's completely surrounded, from every angle, by people telling her that reality is one hundred percent subjective: if you really believe you're a star then you deserve a record contract whether or not you can sing for shit, and if you really believe in weapons of mass destruction then it doesn't actually matter whether they exist or not, and fame is the be-all and end-all because you don't exist unless enough people are paying attention to you. I want my daughter to learn that not everything in this world is determined by how often she hears it or how much she wants it to be true or how many other people are looking. Somewhere in there, for a thing to count as real, there has got to be some actual bloody reality." (153) 
 Someone needs to make a meme out of that.
