Hello, I'm new to the board. I've read the WTM book, and my wife and I "afterschool" my children. Classical education according to the WTM emphasizes literature that has stood the test of time, and I think the article below explains why parents should be wary of modern "young adult literature".

Judging from The New York Times children’s best-seller list and librarian-approved selections like the annual “Best Books for Young Adults,†the bad parent is now enjoying something of a heyday. It would be hard to come up with an exact figure from the thousands of Y.A. novels published every year, but what’s striking is that some of the most sharply written and critically praised works reliably feature a mopey, inept, distracted or ready-for-rehab parent, suggesting that this has become a particularly resonant figure.
