Carrie Pilby is an amazing story, at first I though it was just about a young adult falling in love, who happened to be a prodigy; but is really bigger than that, it's about Carrie and how she changes her perspective of life after getting through a list of things she can experience and would make her happier according to her therapist; the romance ends up as a consequence and not the main event, really far from that (which I though was amazing, since it shows that a relationship isn't what defines her).
Maybe the book is sold in a different way that it actually is, it's not a chick lit, I belive it has too much of a serius analysis about life, ethics, moral, what's right and wrong, which I though was amazing, but can be something that someone isn't looking for when cathes a glimpse of Carrie Pilby. She is an unusual character and it's really interesting to see things by her perspective, you'll probably catch yourself thinking about all the themes that show up.
I guess my only "problem" with the book was that we know Carrie is TOO smart, she graduated from Harvad at the age of 18 (or maybe even less), and maybe this kind of thoughts should have already come to her mind, she reads a lot and is graduated in philosophy, and this topics that she thinks about aren't that incomun and so it's probably something that she could have alredy read and have a conclusion. But I guess having a real life experience can really be a lot different than reading, I still don't have a fixed opinion about it.
