Back in the 1960s there was a book called The Art of Readable Writing, that judged books by the length of individual words and the complexity of the sentence structure, and associated that with an educational level required to understand the book. Some books came out requiring post-graduate studies in the specific topic. I imagine that Lexile is based on some such system.

According to the site, individuals get a score based on their current reading level, and books should be chosen within a range of 100 points below that level up to 50 points above it, to get an expected 75% comprehension. So there ought to be some flexibility if the teacher is using it correctly. However, we don't know what the OP's score was, just what the teacher is requiring.
I did the search for all books by Terry Pratchett and the top three books in order were The Unadulterated Cat, I Shall Wear Midnight, and The Colour of Magic, all 890 or above.
There were quite a few above 725, but also quite a few below. The Amazing Maurice came in as the easiest to read.
I would really like to know who did the "analysis" to determine how difficult the books are, and whether it was done by hand or by computer. You can write a very difficult story using short words and simple sentences.
