Alas, not as good as her other two books. There are four characters fighting for space in this story (literally trading an insult for every nice thing that is said), and in the end, the all-for-one theme of friendship and loyalty seems more of a authorial contrivance than something that meshed organically. 
 The bully-with-hidden-depths was done much better in the author's other book "Dead Ends" (highly recommend that one) and as a result, the romance suffers. The other characters were all kinds of annoying as well, which large doses of teenage stupidity mixed into the plot. While it's not unrealistic, it doesn't always make the most immersive reading. Still, the writing is easy to digest and I finished the book in a day.
