This is the first series I read about the main character being so ambiguous about her looks and ethnicity in writing that by the time I reached the end, I am very certain that Penryn Young and her family is Asian. Young can be a Chinese family name like Yang (Yang /Yang ) and we do love to mess around with romanization of our names (mine too). And it made me very happy after the disappointment with the name of 'Allison Sekemoto'. 
 Much like Larissa Ione's Deliverance series and CW's Supernatural, its about angels trying to make a biblical apocalypse on earth. Unlike various YA dealing with Angels like 'Unearthly', 'Fallen', another 'Fallen' and 'Hush Hush', the angels are a bunch of bloodthirsty son of bitches and don't ever be caught dead romanticizing about them. But of course, it is a YA and romance is practically a minor requirement so we do have this blooming relationship between this kick ass girl and this tortured legendary angel. But nobody should mistake this novel being basic chic lit fantasy YA. 
 But it is primarily about a teenage girl with her crazy mother and disabled little sister who found themselves witnessing angels turning on each other and bad things happened to everyone especially to our two main characters. The story was fast paced and witty but optimism is optional. 
 If you're expecting the book to be another teen boy meet teen girl and happily every afters, be prepared with the amount of death, destruction, blood and gore and dead bodies you have to go through to see an ounce of romance from anyone. After all it is an ongoing-apocalyptic dystopia, where crazy is the new normal.
