 LOved it!!!.. 
 Now to the book cover.....doesn't the girl on the cover look a little like Natalie Portman?!?!?! 
 it made me tingly inside whenever Clara and Tucker would bicker and also 'kinda romantic' moment with Tucker!!!...then the author throws you this 'twist!!!'....Christian being another half-angel and suddenly feeling all lovey-dove for Clara when he came back from his trip after he clearly didn't seem interested!!!
