Deadline for a Dream Book

I wish I had something positive to say about this book. Wait- it accurately portrays how abuse can be cyclical, I guess that's good.

Everything else about it was trash. The writing, the depthless characters, the plot.

*spoilers*_ basically a team of serial killers are brutally slashing people to death, just a lot of torturous cuts before one to the throat ends it. Our protagonist is the investigating hard-drinking female cop who, in the midst of the story, decides to leave her husband for a fellow cop without any real explanation. Like, the author literally dodged the rationale, basically saying "one had better qualities here, the other there, no use comparing, just a feeling, etc."- maybe that's realistic, but it makes for shit reading. Like, she seems completely disconnected from the decision, so if she doesn't seem to know/care then what are we readers supposed to do? Anyways, moving on-

It's slowly revealed that the killers are a couple, their backgrounds largely blank. The guy is kinda easily ignored. The girl was slashed/abused by her mother, and that's what she's recreating. Which, sure, that's realistic, but why'd the mom do it? Who was the mom, what happened to her? And also- why do we care? Like, this isn't really a thriller, it moves rather slowly. It offers no real depth of character, no development, no social or psychological themes besides "London is shit and filled with shit people." Thanks mate, good read that one. Seriously, I don't understand why this book exists- it just kinda revels in the reality of broken people, cyclical abuse, but doesn't actually SAY anything, and it certainly fails to entertain, so.. why? Watch yourself any given episode of Dexter, much more entertaining and, sadly, likely a bit deeper as well.
