What age to start the prequels?

Question:

I have been reading Alice since the beginning. They are amazing. I don’t know HOW you do it, but you do. You’re such an inspiration. I was on the website today, browsing through the fan page and “about you”. I found it so awesome that you’re from Indiana. I am too. It sure is an awesome place. I was also wondering what the age you suggest to start the pre sequels. I can’t wait to get my younger sister hooked on them too! She is 7, but has been reading much older books for her age. What do you suggest?

Your sister should be ready for “Starting with Alice.”  In this book, Alice is in third grade.
