Throne of Glass

DNF
I read the first few books in the series many years ago (when there were only a few books out) but had never completed the series. I thought I'd give it a go now since the series is done and I vaguely remembered liking the books back in the day.
Well I think I aged out of this series...I just read a few chapters into the first book and can't convince myself to finish it. Too bad since I like the concept but the main character is frankly an immature annoying teenager. How the heck did some girl become the most feared assassin when all she talks about is clothes and reading and complains every time she has to do anything remotely physical? Also, she just came back from a year of hard labour in a prison camp but she's totally not affected at all by this!? No trauma response or behaviours, not even internal monologue that would show she's freaking out on the inside but trying to play cool on the outside.
Overall, I think this series is probably fine for a younger audience but the characters are just too superficial and the author doesn't explore the fight to the death assassin competition enough for me. Like I said I remember liking this when I was younger and I know the series gets more politically and emotionally charged later but I just can't force myself to read “until it gets good”.
