I like Falling Kingdoms. 
 ...but I actually don't know who to root for. 
 Three kingdoms. Auranos, Paelsia, Limeros. Four POVs (at one time, five). Cleo, Jonas, Lucia and Magnus. It was hard to track everyone, to tell you the truth. Because just when I was getting comfortable with Magnus, the POV shifts to Lucia, or Cleo. Given that, I am not sure which of them I should give my support, so to speak. But Magnus is the most compelling among them. Intriguing, this prince was. =) 
 So maybe if you like A Game of Thrones, there is a possibility that Falling Kingdoms will appeal to you. The lack of regard to characters is a similarity. Why, you ask? See, the first character who was growing on me, while I'm still on the verge of attaching to him... he was murdered. After displaying himself as a formidable man to watch out for, he has to die suddenly. *grunts* I hate that author's trick. 
 Suffice it to say that I clung to Magnus to give me hope on this rather boring lament of Cleo and maybe Jonas, too. I couldn't care less what happened to them. So Magnus' character... his tortured soul was such a joy to watch. I have no qualms if he's good or bad. I just want Magnus to be this powerful, definitive, and convincing Blood Prince that everyone expects him to be. Bring it on, then. I'm sure Magnus will fit the role perfectly. *evil grin* 
 The few curveballs that made Falling Kingdoms a massive jolt to my system? I'm still deciding if I like them. I think I need to read Rebel Spring to say if this fantasy is worth investing my time and emotions to. I believe it can be better, so let's hope that it will be.
