There were a lot of things I liked about the Sin Eater's Daughter. The first of which, was the uniqueness of the plot. There was a lot of intrigue and it was fast paced. 
 However there were things I didn't enjoy as well. The first of these was Twylla's self absorption, blindness and the fact that she is a bit of a doormat. These issues made the story quite frustrating at times. I was also not totally convinced on whether I liked the romantic plot and the added love triangle. For example, the prince and his feelings about Twylla made no sense as he made no effort to spend any time with her in the past and very little during the span of the book.
