Angel books are a dime a dozen. There are so many of them, its hard to find something special in the mix. Perusing Goodreads I'd noticed Angelfall getting an impressive amount of four and five star reviews. This convinced me I probably should give it a try. I like angel books. I went into this one not expecting to be impressed. Maybe that's why this one ended up being such a pleasant surprise. Its different, managing to clear its own path in angel books. Penryn, the female heroine is brave, with a strong sense of loyalty, especially to her family. What family she has left, happens to be an unconventional one consisting of a schizophrenic mother and a crippled seven year old sister confined to a wheel chair. This book takes place in the future. The earth has been invaded by angels. They have arrived to destroy the earth, determined to eradicate the human race, instead of saving them. Not long after the story opens Penryn's sister is snatched up by the angels and taken away to San Francisco. Left behind is a de-winged angel, Rafe, who she saves because he may be the only link to finding her sister. Rafe is a fierce and beautiful angel. He is a great fighter and a quick thinker. It appeared to me, even from the very start he seemed very protective of Penryn. I guess he felt like he owed her something because she managed to save his wings. Over the course of the story these two develop somewhat of a strange relationship. As the story progresses it seems more and more like Penryn is starting to have some type of romantic feelings for the angel boy, despite her embarrassment about that strange fact. I liked to watch their relationship, if you want to call it that, mature. I was left with so many burning questions about Rafe's intentions towards Penryn after the book ended I sure hope a sequel is in the making. Writing in this one is very descriptive and so easy to get caught up in. The world building was fair. I never totally understood exactly what prompted the angel attack on earth and if they attacked the entire planet or just pockets of the earth. I also wonder if the humans had done something to provoke the attack? The ending felt only like it was settling on a resting point. I felt like a lot of story is still left to tell.
