Good mystery with a bunch of unlikable characters.

The story itself is good enough. The mystery around the murder is tight and in no way predictable. Although it is branded as a thriller novel, the existence of thrill here is almost next to nothing. However, the biggest let down of this is its characters. All of them lack personality. The main protagonist spends a good part of the story just drinking and whining about her ex. The characters are portrayed in an absurd manner. The behavior of the characters is far off from that of any normal human being. For example, Megan, one minute she is talking about her dead child, next minute she is cheating on her husband with her counselor! Characters have no motivation except for sex! The characters are like, this happened, let's have sex! Ow, that happened, let's have sex! And these happen in very inappropriate situations which made me feel really disgusted. In a nutshell, the characters are uninteresting, boring, and even irritating to some extent. The plot was good but the characters just threw me off the story.
