I won an ARC for this book in an online giveaway - I believe it releases early 2017. 
 My rating - 2.5 stars. It was a light, enjoyable YA fantasy read but didn't really engage me. 
 There were a lot of cliches cropping up without enough of an original take on them to intrigue me. The characters were likeable but a little flat, the plot was disjointed with elements that seemed to have little relevance to the overall story (or at least, not enough to justify the time spent dwelling on them). And I'm sorry but info-dumps that massive and obvious just put me right off a book. Ugh. Interesting worldbuilding, with the interplay between legend and history, but there were plenty of ways that information could have been drip-fed and/or pared down to the essential parts, without having an otherwise entirely unnecessary and without consequences deviation to the main plot. Despite several pretty important events occurring in the first part of the book (some of them, unfortunately, pretty cliched as well) the story really didn't feel like it was going anywhere until about 100 pages in. 
 Most frustrating was the patches of potential. Some of the character development was actually quite good, both individual characters and in terms of their relationships. But then they just went back to same-old, same-old again. The Frostblood king could have made an interesting villain if he'd had more page time, or we'd known more about him, but as it was his contribution to the story felt rushed and forced. It's almost like there wasn't actually an antagonist for the first half of the book - or at least his presence wasn't felt enough to give the story any real tension. And likewise, there were parts of the book where the writing zipped along and the plot got intriguing - but they were rushed or skimmed over before we went back to cliches, problems were resolved too quickly, and too much of the writing lacked a distinct voice - which as it was in first person, makes it hard to really gel with the protagonist. 
 I think the series as a whole could still have potential - this is a debut book and almost every author I've read has room for improvement on a debut - but I don't know if I'd prioritise finding out over the millions of other books on my TBR. If you're looking for a light, quick, escapist read, this is pleasant enough. If you're a die-hard fantasy fan looking for your next fix, you'll probably end up frustrated.
