Yes, she's my sister, but I'm also hers. *points to the pink female sign by gender and to her profile pic*
Anyway, so I'm not accused of being completely off topic again. I introduced my sister to the series last summer when I read a chunk of them out loud to her. It was fun and when I went back to school she kept reading them.
I'm trying to get my brother to read the series (he's 2 years younger than me). He read a few but said he never really got into it.
