That is, *if* that's the only novel/work she copied.
Even if that's all, that's over a page's worth of work, spread throughout the book, which, to me, is a lot.
I don't mean that it's not a lot in terms of plagiarism- it is, and I think MM would be justified in taking some kind of action. I'm not trying to minimize the seriousness of it- I'm trying to put the amount of "work" or "time" it would have saved her to steal these bits into perspective. When you're writing a 320 page book, it's not going to save you a tremendous amount of effort to have a page of material you get from elsewhere. Even if the author did this with four or five different books, she'd still be left with at least 310 or 315 pages that she had to write herself. It's impossible that any kind of majority of the book could be lifted from other books- it just wouldn't be doable.
So the question I'm asking myself is why would anyone do this? Why risk everything for what amounts to saving you very little time or work? There are really only three answers: either she did it on purpose, but didn't realize it was wrong, she did it on purpose, realized it was wrong, but didn't think she'd get caught, or it was somehow accidental. There is no way that someone would do this, think there was a decent chance of getting caught, and do it anyway- if you thought there was ANY chance of getting caught, the benefits would be far, FAR outweighed by potential risks.
I can't help but think that however this happened, one of the major contributing factors was the way in which this deal was offered. The author was referred to a literary agent by her college counselor, and they "discussed" and "brainstormed" a proposal, which suggests (to me at least) that Opal Mehta was not a work that the author had started writing before the meeting. They later sent four chapters and a synopsis and it sold based on that. Little, Brown then sent Kaavya to a packager, to help the seventeen year old with the book. I read an article in which her editor was quoted as saying there was "more shaping to this book" than most of the books they do.
To me, this all sounds an awful lot like they found a kid who could write and had a decently interesting angle (the Harvard thing), and they sent her to a packager to make the book into a more widely appealing chick lit book. She was getting input on marketing from all sides before the book was anywhere near finished, and I'd bet a lot of money that she was under pressure to up the chick lit aspects of the book.
I can't imagine writing a book this way, ESPECIALLY your first book. If you're getting that much input and influence from different places (the agent, the packager, etc) before you've written more than four chapters, how much of the book is going to feel like it's really yours anyway? I think, that if you want to trace her motivation back to pressure somehow, it may be more the pressure to "write the book LIKE THIS" rather than just the pressure to finish writing her book.
Not, of course, that any of this excuses the plagiarism- I definitely don't think it does. And I really hate to think how this might change public (or industry) opinion towards teen authors in general...
