The level is Boxcar Kids, Nancy Drew, RL Stein etc. Some suggestions have been hugely useful, some will be useful in middle school. No big deal.

I've already downloaded all the series she likes so I'm willing to put things above her reading level (it's not like she won't learn to read at that level eventually).

It was a good catch though that I was asking specifically about reading level and not just age. For her age she's about average, thought she does lag in math (I'm making sure she picks that ground up), but she does have the blessing of enjoying books.

Giving her a respect for rationality and science would be nice. But really I'll be happy if she stopped talking about the Bieber. I just can't compete with the guy's hair helmet.

EDIT: In Before Ender's Game is higher than her reading level.

I know. I know. I'm putting your above reading level stuff in there too. She'll have a small library in her pocket and I'll forever be the favorite uncle. Muahaha.
