This book was way better than I expected. There's some really cool worldbuilding in here that the synopsis only hints at. The whole witches predicting the future is cool and all, but magic that is harness by singing? I can really dig it. 
 There's a rich history to Coakley's world and I was really disappointed that there doesn't seem to be more books in this series. Because I could definitely do with more. 
 My only gripe here is that (view spoiler)[I really needed Ryder and Falpian to kiss. I just. There was such wonderful tension and build up between them. And I mean, come on, brothers in spirit whose people are enemies? Basically soulbonds and actual facts telepathy. There was even a moment where Ryder needed to be silenced and it should've been done by kissing oh my god what a wasted opportunity I just. (hide spoiler)] And of course there is no fanfiction to be found on the internet. SIGH. 
 Anyway. This was fun. If it sounds interesting, I'd pick it up.
