So I was pretty reluctant to read this book--previous books I've read that has to do with angels and stuff weren't the best for me--but it was a nice read! Some interesting attributes are that angels not only have wings but have "glory". Basically, they get all bright/shiny (this scares humans) and are pretty much in tune with all their surroundings. 
 Clara is a quarter angel-blood (her mom is half and her father is human), but she's very strong even with her diluted blood. Visions of her "purpose" (or her sole reason of being here) has been constantly occurring. The vision is of her saving a boy (Christian Prescott) from a forest fire, but she has trouble figuring out the details. She and her family (only mother and younger brother; her father left when she was little) move out of California to Wyoming all because that's where her purpose takes place. She meets Christian at school, and he's the cliche popular jock with a popular girlfriend.... And I don't want to reveal more because it'll spoil the book. Even if you're "iffy" on this book (like I was), I still suggest you pick it up!!
