4/5; 4 stars; A-This was a really well done thriller/mystery. I haven't read anything by this duo before so it was a good surprise. I really liked the complexity of the mystery and how the two story lines wove together. I am interested to read some more in this series.The one big glaring hole which knocked my rating down was something that started out early in the book, kind of got pushed to the background but became really obvious in the last part of the book. I just could not believe that the cops could completely overlook the fifth person connected to the Monkeewrench group. It was like she didn't even exist.
