I finished this hours ago. And I keep debating how many stars I could...should give it. 
 Is hard for me to give this 3 stars. But Sadly I didn't loved it, it was nice. Like a fairytale. Simple. Don't get me wrong! The writing at times was poetic, sweet...but the caracthers. I just couldn't understand how Lark could love someone that for me, didn't really loved her. A pity that for me, the love from him to her was, using some Lark's words, pale and insipid. Maybe, maybe, I feel this way because I needed more time and pages to see what others seem to grasp. Also, I was expecting this huge thing towards the end and never got it. 
 The prologue was strong, the beginning too, but at some point...just...nice. Then came the epilogue and even tho it was great. I still felt that I never got the feeling her king loved her. 
 I guess I just wanted a more kickass, a more building and more proof that he deserved her. 
 Anyway, I would still recommend this book. Is a sweet tale of a invisible girl with fire inside her, hungry for love and in the need of freedom.
