Twilight as a test prep book.
.....Huh?
How on earth is this possible? Yes, Stephenie Meyer knows how to use a thesaurus, but many times throughout her books she MISuses the words. She uses them in the wrong context, she excessively uses some words ("dazzle" and "murmur" are used way too many times) and this is only talking about her word choice. Her grammar is atrocious, and is convoluted and horrific in places. Not to mention the sexism and classism prevalent in the series.
Just look at this blog, http://reasoningwithvampires.tumblr.com/ which conveniently analyses and pinpoints the many, many mistakes and problems in general of the series. If this Brian Leaf is going to make a test prep book, he should at least base it off of a book that has some concept of, you know, editing.
But then again: the book sells, the people using it probably aren't smart enough to notice the atrocity of Twilight as it is, and the book sells.
And I guess that's all that really matters (to Brian Leaf).
