"Boring and comes to no conclusions"
The author just quotes from other peoples research. There is no passion behind the topic and is merely a dull collection of facts from haphazardly conducted research. I could not finish listening as I couldn't make it seem worth my time - not worth it!
"the story that tried"
No. At least not a sequel in this series.
The best scenes were the dauntless training and initiation related. The paintball scene especially.
Every single love scene between tris and four. They were sickeningly erotic, and downright dirty. There is one scene where I'm almost sure they had sex, but I skipped to the next chapter. those scenes were also cheesy.
