Yes, I think that the reading level wouldn't be too hard for a strong reader, but I'm planning on waiting on the mysteries. Gives her something to "graduate" to after she finishes all the core and short stories. We still have to finish Kit, Molly and Josefina. Haven't even started Samantha, Kirsten, or Kaya. She read all of Felicity b/c she got the boxed set for Christmas, and she doesn't know I've finished off her Kit set yet, so she will be finished with those soon, I think.
