I have finally finished this novel and I have to admit, this novel lacks the magic of Dessen's other books. Admittedly, reading this novel as an ebook that had super weird formatting distracted me quite a bit but I felt that story-wise, This Lullaby didn't meet the high standards of say, Along for the Ride or Lock and Key. 
 Remy is a highly cynical person, no thanks to her mother's five marriages, but really, I think her whole attitude towards boys was what turned me off quite quickly. All I could read about her was that, "I don't fall in love. I don't form attachments. I just use boys." That's it. 0.o Also, I found our male lead, Dexter, a little creepy. Of course, one might argue that his actions can be brave and even, endearing but personally, a boy who just comes up to me and writes his name and number on my hand is someone suspicious. Climbing through a girl's window unexpectedly, girlfriend or not, is also creepy. 
 The whole premise of "This Lullaby", a song that Remy's deceased birth father wrote for her, sort of as a legacy, was really underused. There were numerous mentions of it, of course, but really, it just kept touching on the same thing: Remy has animosity towards this song, and thus, she has a no-musicians rule. 
 The ending is rather ordinary, but it's something I'd expect from a Sarah Dessen so it wasn't too bad. Better luck next time, I suppose. 2.5 stars out of 5.
