I think I am the only person who really, really did not like this book. I don't want to poop in your punchbowl, but I did write a review of the book, and these are my issues:
The first is that the book begins so confusingly. Yes, there is pay off for the obscurantist beginning, but it was far from the most engaging way to begin the book.The flashback storyline that starts in the prologue is told in a (possibly deliberately) confusing and difficult to follow way. However, I did unravel the book's mystery about halfway though, long before Taylor, the protagonist, ever did, and she had a lot more information than I did. Made me wonder why a character depicted as so sharp was so dense when it came to this matter. Marchetta gives her selective amnesia about her past, but I found that rather ham handed and contrived.
My main issue with the book, then, was all the secrets. Why not level with Taylor about her family? Why keep the kid in the dark about who her father is and how he died, who her aunt is, just exactly what her mother is up to, and who the Brigadier is? She was obviously tormented by the mystery, but instead of telling her, her beloved Hannah just disappears, nary a word. Her mother had also abandoned her, and no one tells her anything. These adults, who we are to believe love her and each other so much, lie to her for years through omission despite her burning need to know, so deep that she ran away to try to get some answers when she was 14. None were forthcoming even after she pulled that stunt. Do people really treat children they love this way? And to what end? She knows that everyone around her has more information than she does, and they just dole it out in little dribbles, surely a technique that it meant to serve the plot more than it is to serve as realistic character development. It made me think all the adults in the book were huge assholes, frankly. It's Star Wars-itis, or maybe Wizard of Oz-itis. Lie to the kid for no good reason and still be considered a beloved authority figure. I despise this trope in young adult lit.
I felt like, in the end, Marchetta created and perpetuated a mystery for the sake of a big, dramatic reveal-- and it was, and it was moving, but as I often find with YA lit and movies, the adults behave badly, keep secrets for no good reason, all for the sake of the author's darling, the big cathartic ending. At least Jonah Griggs has the decency to hate Hannah for her deceit.
I could also mention that every single childhood trauma imaginable is thrown into this plot (dead, unknown parents; absent guardian; child molestation; kiddie porn; child abuse; patricide; cat drowning; child abandonment; teen suicide; a child witnessing a suicide; a huge fire; a junkie prostitute mother... etc) Yeah.
But what do I know?
