As you may recall from my review of book two in the series, I hadn't originally planned on finishing this trilogy. But I already owned book three, and I sort of cared a little about the conclusion, so I went for it. 
 Skimming my review of Rebel Angels, I have the same issues now (No, really, all the same could be said over again). I still don't understand the friendship between the three girls. Felicity and Ann are blatantly using Gemma. Why doesn't she notice this by now? Gemma has all the magic of the realms within her, and she's completely selfish with it. She claims to hold it until the tribes can make an alliance, blah blah, but really she's using it to improve her own life. (Which is exactly what she didn't want the tribes to do.) 
 Despite all that, though, there are good points. The banter between Gemma and Kartik never fails to bring out my inner romantic. And there are some great action-filled scenes toward the end (I won't get into details) that you genuinely have no idea how they will conclude. And when it does conclude, you don't believe the way it happened. 
 I would have been disappointed if it had your typical "happily ever after," but it doesn't. Some bad things happen, some good, and that's a better conclusion than if everything was tied up in a neat little package. And you may hate the way some thing ended up, but that's the point. It's more realistic. That's life.
