DNF'd at 100-ish pages

I've been trying to read this for over a year and haven't managed to get past the first 100 pages so I've decided to give up.

The plot had the potential to be interesting but nothing about the characters or Kendare Blake's writing grabbed me. I also guessed the ending within the first couple chapters.

Spoiler

Katherine and Arsinoe both sucked at their talent so I pretty much immediately figured out that they had each others' talent. And guess what I found on the last page: Arsinoe saying that she's a poisoner.
