I don’t think those books are on the Index or anything, so I can’t speak to the Church’s official position, just my own after having studied children’s literature at the Master’s level. So much great literature exists for the 11/12-year-old group (you know, in the
children’s section of the library and bookstore).
The book goes against Church teaching. It has terrible writing, weak themes, and inappropriate graphic content - at point even sexual, if I recall, which I don’t particularly want to). Generally I don’t like banning books or systematic barring of access - parental is ok

- but I feel comfortable saying such material shouldn’t be mandatory reading or even
suggested.
Want to get a great reaction? First, go to the local bookstore and library and compare the summer reading list for your daughter’s grade with those of public schools. Having been in the business and living in a very liberal town in very liberal New England, I am annually pleasantly surprised at the inoffensiveness of the public school’s book choices, usually culled from Newbery Award winners in the childrens’ sections and maaaaybe some early YA that avoid sex. If you find the same in your area, you ask the teacher, principal, and Archdiocese superintendent why
they are the ones offering up smut to our children.
Call up the other parents. Call up your parish priest if the school is diocesan. In fact, message me the school’s address, and I’ll write letters on your behalf if they won’t change their position.
If it’s done purely from the misguided notion to make them aware of fallacies and heresies, there are much more appropriate and less confusing ways to teach that, IMHO.
