Things seem to have changed since Trixie Belden.
From the Blurb:
Until now, you have been just plain old Janey Brown. But you are going to grow and grow. You will be what your parents have not allowed you to be. It's in your past. And it's in your future. There's a whole new part of you just waiting to burst out.
You are JANE BLONDE - sensational spylet. Welcome to our world.
