Wow. I have A LOT to say about this novel. This is absolutely the best collection of short stories that I have ever read. Like other Veronica Roth books, this one is also fabulous. Personally, my favourite was the first one, Inertia. Do check it out and do buy it. I would warn you though that the last two chapters are part of the Carve The Mark series, but I don't think you have to worry about that as the short stories give enough introduction. Solid 5 stars. Do read it. You'll thank me.
