Just a Few Inches is a book that's strongly focused on the moral at the center of the story.
It's a good message too, one that needs to be more prevalent in today's society of always striving for the perfect body image. One of the better aspects of the book is that it frames body image in a rather striking and dramatic way, through the use of fantastical elements that would otherwise be impossible in real life. The desire for a perfect body causes Carrie to start taking diet pills, which has the extremely odd side effect of making her shrink - literally. While at first she's ecstatic to be losing weight, she quickly realizes she's not losing weight how she imagined it - she's losing height and mass.
Throughout the story, we follow Carrie as she struggles to deal with this extraordinary circumstance. Clothes become loose. Reaching tall objects becomes harder and harder. And as she loses more and more height, her difficulties surmount, until just reaching doorknobs becomes an issue, and something like climbing the stairs is an exhaustive process. Eventually it gets even worse than that.
The only time I've ever encountered a plot turn like that is with Honey I Shrunk The Kids and a few cartoons and kids shows here and there. Here, Tara St. Pierre really delves into the aspect of shrinking and the challenges it would present, and how scary it would be as it progresses more and more.
However, even as she becomes smaller and smaller, Carrie manages to gain new perspective on her life and the people around her. She uses what happens to her to open discussions on body image. She uses her newfound fame in the public eye to put forth a message of positive body image, and does what she can to turn it into a positive event for others, even if she's terrified for herself. She grows closer to friends and family, even through the hardships.
Carrie's character is the strongest aspect of the story. We spend a lot of time with her, learning her hopes and dreams and getting to know her voice. We see the story from her perspective throughout the book (no pun intended) and it's a fun one. Unfortunately, because it sticks so closely with her, some of the friendships feel a little underdeveloped at times, but not to the point where it was an issue with the story. I do think that Carrie was a bit too forgiving at times of what other people end up doing to her. Given the circumstances surrounding her, I can understand, but there's a few things that people do that go unanswered, including something with a little girl later on in the story and what a rival does.
As I mentioned before, ultimately the moral is the thing that's the most prominent aspect of the story. There's still issues with the story itself, however. Given that the message is the focus here, I don't feel right docking a lot of points for it, but I feel like it should be pointed out.
The use of the diet pills is an obvious plot device, and that's fine. But it facilitates several problems with the internal logic of the story. Now, like I said, this is obviously a fantasy story - but several times it straddles the line between being a fantasy story and trying to explain events in a realistic manner. The diet pills are the plot device that gets things moving. Several times throughout the story, doubt is expressed over whether or not the pills are to blame, and that was fine...up until another woman comes forward and admits that she lost a few inches because she took the pills and was told to keep quiet about it in exchange for a deal with the company, just like Carrie.
That's kind of a problem. If it can happen to others, as evidenced by this woman who shows up and vanishes in quick succession, then why hasn't it happened to more people? It's hard to believe that a lone teenager would the only one in the nation to take a higher than recommended dose of diet pills.
There's also the problem of consequences. The story culminates in a trial with the drug company where Carrie confesses what happened and why she took the pills, and too many of them at that. Ultimate the resolution of the trial isn't revealed. I kind of think that the pills and the trial itself aren't needed for the story at all, much less the mysterious woman who only lost a few inches. The shrinking doesn't need a reason. In a fantasy story where the moral is ultimately the most important thing, I would be satisfied with the fact that it just happens. Maybe it's caused by her desire to fit into the dress and it goes overboard because of the glut of media out there body shaming women. Maybe it's some weird genetic disorder that no one has ever heard of, or maybe there's just no explanation at all. It wouldn't really matter.
I also wondered - where was the government during this? The story has a trial and she's public knowledge, but the government seemingly never gets involved, which feels kind of weird. It wouldn't be an issue but having a trial made me wonder. The same is true for skeptics - everyone in the world seems to kind of just accept it - that's fine for people who see her in person, but online, there'd be a lot of skepticism over it and probably a lot more people crowding outside her house trying to see if it was true.
And finally, the ending. It just kind of happens.
Carrie gives her speech, she accepts herself, shrinks a little more, and then begins growing. Most of this is presented in a summary. Everything works out fine and all the characters get what they want. It's not necessarily a bad ending, it just feels lackluster. We spent a LOT of pages getting to know Carrie and seeing her struggles, only to have it resolved in the span of three pages that feel like the epilogue to the Harry Potter novels. Short and unsatisfying.
Do we need to know why she stopped shrinking and then started growing again? No. Did I want to know anyway? Of course. I didn't dock the book any stars for this, but it's so quick and so glossed over that I wanted _something_ more.
Overall, I'd recommend the book. The moral is heavy handed, the logic struggles with the unrealistic nature of the circumstances and the moral being presented, and sometimes the characters feel cliche. Carrie is a charming enough character that ultimately it doesn't matter, and if you can get past the above issues, you'll enjoy the book as much as I did.
