FAQs

What's the reading level?

- It has an ATOS rating of 4.8, that means the book is perfect for 4th and 5th graders, but might also be a great fit for younger and more advanced readers. It's been used in classrooms from 3rd grade up to 8th, which means it is both accessible and appeals to a wide range of ages (see the quotes below from young readers, teachers, and parents).

Can I start with any book in the series?

- Yes! Each book has an introduction that catches readers up on the bigger story and without giving away spoilers from earlier books. But, we do recommend that you start with book one for the best experience.
