The kinds of novels I read aren’t really given to plot twists or surprise endings, and non-fiction certainly isn’t.
The only book I could think of for this one was Mockingjay. I don’t know if it was completely surprising but it was like “Damn, Suzanne Collins. You went there.” It actually felt like how things had to end for Katniss, honestly, but so many authors would have tried to soften it. Pulled up at the last moment. I was surprised that she so unapologetically wrote what needed to be written.
I am deathly terrified to spoil anything for those who have yet to finish the series, but for those who have read it I will clarify to what “twist” I am referring. The entire segment of the novel from sewer lizards to Coin’s speech.
A lot of people found this book a disappointing conclusion to the series, and I have to say I don’t get that. I found it completely fitting. My only guess is that they hoped for a happy ending, or thought Katniss was strong in a way that she wasn’t and were disappointed to find she was only human (and a very damaged one at that). The third Hunger Games novel was heartbreaking, but it was never a fairy tale to begin with.
