A book that gets progressively worse the more you read. Poor characters, plot and dialogue. I found Jacob thoroughly unlikeable and the characters paper thin, and while the language may be 'young adult', the writing was infantile.
While the story was poor, the unforgivable sin in my eyes is a book that clearly isn't going to finish in any satisfactory manner until about book 3. Series are fine, but please have a bit of skill and create an enjoyable yarn within each book.
I'm afraid I won't be reading any more of these.
