Try putting it in present tense, no matter which tense the story is written in. It gives the blurb more immediacy and will sound more intriguing. The other thing, you finish the description with a rhetorical question. If your books ends with the teacher telling the hot hound stud that he is acting inappropriate and they maintain professional relationship, that would be... not like 100% of books go. So, instead of the questioning the reader about your book’s content, I suggest a strong statement that will sum up the stakes: what is the worst thing that could happen to Brooks, what does she need to avert it, what should she learn in the course of the book in order to avert it?
