stories to remember

Today I was out shopping for a present for Angelina. For the last couple of weeks I've been looking for books for her. She likes to read. But I'm not familiar with what's hot and not for a 7 year old. What I ideally want to buy her is a subscription to a book club or something like that. I remember as a child, my parents had bought this package where each month we received Dr. Seuss or Mickey Mouse books. They weren't thick books but by the end of 3 years we had a whole bookcase full of books. Plus it was fun waiting for the next book to come in the mail. I went to Scholastic's website - as they seem to be the leader in children's books. I ended up getting a book each from 3 different series to test with Angelina - to see if she likes them. Any of you teacher-folk out there have any recommendations on children's book clubs or books in general?
