I LOVE to read, so my daughter is a bit of a mystery to me since she never voluntarily picks up a book.
My hubby is a professor, so he reads all the time, but he rarely ever reads fiction and I rarely read non-fiction, so we tend not to read the same things.
My son loves to read. He's in 6th grade, and he does like it when I read the same book as him because he loves to talk about them. I read about 5 of the Warriors (cat) series at the same time as him but I just couldn't keep going after that.
