Or probably 4.5 :) 
 This book was seriously a great story. It was interesting, intriguing and definitely one of the better angel stories out there (no question - although still under Angelfall by Susan Ey :P ) 
 The plot and characters was developed amazingly well, as was the writing. It was a really long book though, like really long, almost 550 pages on my e-book-reader. The start of the book was a little slow for me (Aimee could have delved into the story a tad quicker but I guess the start was a good foundation for the preparation of the story) but it was well worth the read in the end. 
 The romance was pretty good too. After having read one too many reviews I knew who she'd end up with in the end so I guess that kind of took away the flair of the developing romance for me (but it was still well written but didn't have the same spice as some other romances I've read. 
 All that said, I'd definitely give this one a read! Especially if you're looking for another angel book :)
