Stop me if you've heard this before. Semi-pretty teenage girl goes on mission to save someone/retrieve something/etc, finds hot guy, abandons entire quest because of his sexy smile and killer abs. Well, you'll find none of that here! When Paige, Penryn's younger sister, is kidnapped by angels who have destroyed the world, Penryn springs into action. Even when she meets oh-so-hot angel Raffe, that doesn't deter her from finding Paige, no matter how pretty he is. (And we're told many, many, MANY times how beautiful Raffe is and how he's not human. Broken record levels here.) Then, lo and behold, she actually finds Paige! Mission complete! This was such a breath of fresh air from novels that give the female protagonist a goal that she will promptly abandon for a pretty face. 
 Where this novel falters for me a bit is when they get to the aerie and these are tons of angels hanging out in a ritzy club with human women fawning all over them. It took me out of the story and threw me back to when I watched the final season of Fringe. If you have not watched Fringe, spoilers abound: (view spoiler)[Throughout the series, there was a mysterious group of pale, bald men called Observers, who seemed to, you guessed it, observe random events. In season five, these emotionless, passive, mysterious people come from the future and take over the world. You catch scenes where they're hanging out in clubs with women swooning all over them. Seeing as they don't have emotions, only rational thought, this makes absolutely no sense. (hide spoiler)] It is the same in Angelfall. Why are angels partying and letting women rub up on them when they seem (and this is pointed out) completely disinterested and would rather converse with other angels? This was the only problem for me, although since we aren't shown anything about the angels and their hierarchy, hobbies, etc besides what Penryn observes and Raffe tells her, there could be a reason for all this. 
 While this book didn't wow me and make me pump me fist in the air screaming "GIVE ME MORE" while I ran to the nearest book store, it was a good story and I would recommend it.
