There’s good and bad parts of this trilogy, and a large portion of the good ones happen in the first book. Which isn’t to say that people shouldn’t read them all—but the first book is the best, in my opinion.
I know the story well by now, having read the first book a couple times and having enjoyed the movie. It’s pretty fantastic, the world that Roth created. I love the idea of the factions, even though it all seems to be a bit flawed in practice. I like to think I would be Dauntless, but then, bravery is a most desirable quality, if we consider the number of Harry Potter fans who want to be Gryffindors (whether they actually would be or not). Tris is great, too, as far as protagonists go. She’s strong and smart and very brave. Almost too smart, though.
Roth’s writing takes a little getting used to. Her sentences are short and to the point, which keeps the pace up. It’s similar to Hunger Games, but not quite as good at keeping me 100% invested in every detail.
Following in the wake of the Hunger Games craze, I’d say Insurgent isn’t quite as good. But then, Suzanne Collins is hard to beat. Anyone looking for a brave female protagonist who drives a lot of action sequences and fulfills the “chosen one” role will probably like Divergent. There’s some romance thrown in for flair, and I actually really like Four in this book. He’s dark and still mysterious, something that we lose in books two and three. Dystopic YA sort of blew up after Hunger Games made it big, and there’s a lot of not-so-great stories out there. Divergent is solidly in the you-should-read-this-even-though-it-isn’t-quite-The-Hunger-Games camp.
