After having such a great debut novel it can be hard to top it. Sadly Thief Eyes doesn't really have the innocence, wow factor, or plot element that Simner's first novel did. 
 For those that don't know Icelandic lore (and I'm guessing that the MAJORITY of the US Teens don't). This book is going to be confusing and a bit hard to understand. I had some knowledge of lores but not enough that it was an easy read. 
 With that said, it was a unique choice Icelandic lore and that made it intriguing. Maybe more people will look into it after reading this (so they can understand what they read). 
 simner's writing is very descriptive, lyrical and flowy. A lot of descriptions of emotions, and lands which could turn readers off. 
 The romance that was in this novel just didn't work for me. Too fast, not developed enough and extremely forced. I could see it coming from the first time they met. 
 Another thing I don't like is the whole bad father's thing. I don't get why this is a trend. 
 Plot wise this book moved very slowly and didn't have much to it until the end. If the ending was like the rest of the book I would have loved it. The events that happened and the whole magic thing was a tiny bit confusing and hard to follow. I had a hard time understanding what had happened, or was happening. 
 So while it wasn't a bad book it just wasn't as good as her debut and I really feel it could have been a bit better.
