I’m thirteen years old, and I absolutely love your Alice books! One reason I love them is because I can relate to Alice and some of her embarrassing moments. I’ve read all of the Alice books, up to Dangerously Alice. Alice is getting older, and I was wondering if there’s a point in the series where I should wait until I’m a little older to read them. Thanks for your time!
At thirteen, I would think you’re emotionally mature enough to handle anything coming up in the Alice books. The bigger question would be if you would like to read only the three books each year in which Alice is the same age you are. If you want to enjoy them all in one big gulp, go ahead. You can always read them again later, as most fans do.
