So this story is fairly simple and generic, and it's written about in excruciating detail. I did appreciate that there's little to no logistics holes (except for the society and technology and arc not progressing in a 1000 years). Some of the writing had repeated words and expressions that were a bit annoying. I honestly don't know why I kept on listening for so long, but somehow because everything is extremely generic, it's also pretty relatable. Except when Zara is mistrustful and bitchy for no reason for all of book 3 and a little before and after too. All of the book necessarily has to involve the two main characters since we mostlysee things from their perspective, which means that for a lot of the book the world seems kind of claustrophobic, not even counting that they literally live under a dome of fixed size. The main characters have little back story too, Zara only turns out to have a living parent in book 4, which she is all of a sudden very worried about even if he was never mentioned before. Owen doesn't seem to have bonded with anyone at all during his training, or at least from the time he was 14-15 when he went to the rangers, until we find him with Elias (which he has been with for 6 months, and he's like 16-17ish?). My biggest pet peeve is how spectacularly useless the magic seems to be. It can do fire, shields, elevators and restraints, that's it. There's mention of other stuff, but it's never used in any way. 

I was interested in the book for a long time but I'm glad it's over now. I don't think I'll read anything from this author again.
