The first half was just skim. It distinctly gave me Twilight vibes for some reason. I didn't really like the way their relationship started. It was too unrealistic, and, meh I was turned off by it quite a lot throughout the book. The vocabulary, to say the least, is quite colourful.
The second half was more bearable.

•Plot- or character-driven? Character (And, please provide some justice to Johnny and his friends' names, they were so childish. Gerard's fine, but Gibsie? Nope....Hughie, Feely, Johnny...Why?)
•Strong character development? Sort of, but not much.
•Loveable characters? Yep. Well, this pushed me to finish this book.

Highlight:
I was, like, what am I reading- most of the time?
There was quite a lot of repetition of dialogues, situations etc. I was kind of bored by then.
And, why was it so unbearably long?
Overall, it was fine, easy to read and nothing much further. Non plus Ultra.
