This story's visuals of the breathtaking fear of Angels Landing and the awesome beauty of The Narrows is spot on!" - Mike Devine, Grandfather of two National Park-loving grandkids, Florida "I continue to love reading this series to my kids. Having explored over 50 state and national parks, my kids love the adventures and the riddles. I appreciate the relationship the kids and parents have and the trust as they work together and explore the parks. The beauty of these books, with both descriptions and drawings, can't be beat." - Nancy Lee Zimpleman, Mom of Two Ultimate Outsider Campers, South Carolina "As a kid, I wondered why so many kids' books left out the parents. I thought it a bit strange. So, as an author, I decided to make Jake, Amber, and Wes's parents real characters in my stories. And in doing so, I've learned why most authors cut the parents: It's really difficult--especially when you have six parents! But there voices are essential for the kids to learn and grow. That's especially true in Book 4: Danger in Zion National Park. The story has real place, read adventure, (and even real parents ;). I hope you and your family enjoy reading it, as much as I enjoyed writing it!"  - Author a
