FAQs

When does this ship?

- The books will ship summer of 2026. See progress page for updates.

- Stickers and bookmark will ship in a separate envelope as soon as we have them in stock.

What's the reading level?

- I've written the books for ages 7-14. They have 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.

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.

Our absolute favorite kids series!

Our absolute favorite kids series! My husband and I fight over who gets to read to the kids nightly because we’re both so enthralled with the story and don’t want to miss a beat! They’ve also inspired our efforts to follow his path as we tick off our own national park adventures. Keep up the awesome work! We cannot wait for book 6!!

Honestly, one of my top 3 book series.

i won’t say what my other 2 top series are, or what level this one is, but honestly, i can’t believe these books are sooo good! I literally stayed up PAST 1:00 AM reading the first book, they’re so awesome.
