Query: Parents BEWARE! Lots of sexual content.

These books are touted as "teen" books, but are highly sexual and completely inappropriate for young people. I read one just to keep up with what my 13-year-old stepdaughter is reading and could not believe that her mother allows her to read this trash. Passages where teens are kissing, then "moaning", then "moving on top of her" are common. This is adult material, not suitable for teens.
