Sex-free, Drug-free Books for Advanced, Immature Reader

helpHelp for my special needs kid!

My daughter is 12 but has a brain injury due to bio mom's use of alcohol and drugs prior to birth (it's called FASD). She is very smart and an advanced reader but goes to a school for kids with special needs. She's very very immature but thinks she's 28 and never stops talking. It's a struggle!

We need lots of recommendations for books she can read that are at the level of a pre-teen in terms of depth and syntax, but that are free of sex, drugs, alcohol consumption, that kind of thing. It's not because we're scared of exposing her to that stuff, it's that she has a tendency to talk about everything she reads and can't screen herself in front of the other, more impressionable kids. Then we get phone calls from the school, etc. You get the idea.

So: YA novels that have no sex? Example: she recently read Hunger Games series and LOVED LOVED LOVED it. Something along those lines? Thanks!
