I’m going to say it right up front: the reason I did not like this book had nothing to do with the ending.
Well, almost nothing. The ending was what she was building up to, and since I had a problem with the build-up itself, I sort of do have a problem with the ending by extension, but that’s just semantics. Actually, I was so burned by this series after Insurgent that I wasn’t looking forward to reading this book at all, so when I accidentally spoiled myself over THAT THING before I had even cracked the spine on my brand new copy, it had the opposite effect on me it had on most readers. It actually made me more excited to see how she was going to pull it off. And I was still disappointed. Sigh.
I do have to give Veronica Roth credit. She may have fumbled the execution (a lot, in my opinion), but I do think she had her priorities straight. She was dedicated — perhaps too much so — to seeing out her themes and serving the narrative, as opposed to taking the easy way out in the way she ended her story, which is what her readers wanted her to do. The problem here is that the structure of this third act in the story is just a big old mess, and the way she crafts her words and her sentences and her dialogue, I think, actively worked against the goals she was shooting for.
From here on out, be warned, spoilers ahoy.
Let’s acknowledge the elephant in the room: Tris totally bites it. She croaks. She is annihilated. She goes belly up. She buys the farm. She’s checking out the grass from underneath. She goes the way of the dinosaurs. She’s popped off. She’s permanently out of print. She’s shuffled off the mortal coil.
She’s stone dead.
