Brynn Walker promised herself she was done with secrets.

After everything that happened in Vernal, she is trying hard to prove she can be trusted again. No sneaking around. No dangerous discoveries. No mysteries that get out of hand.

Then Brynn finds an old map hidden inside a donated fossil book.

The map points to Red Rock Ridge, a stretch of sandstone cliffs outside Vernal, Utah, and marks a cave that does not appear on any modern trail map. At first, Brynn thinks it might be an old fossil-hunting clue. But when someone else starts searching for the same cave, Brynn realizes the map may lead to something much bigger than fossils.

With her best friends, Tessa and Max, and her loyal husky Rex, Brynn follows the clues into the cliffs. Inside the cave, they uncover old markings, a hidden chamber, and the truth about a long-lost journal that someone has been trying to keep buried.

But Red Rock Ridge is dangerous after sunset.

And Brynn is not the only one determined to find what was hidden there.

The Caves of Red Rock Ridge is a middle-grade mystery filled with friendship, courage, Utah desert adventure, and a secret from the past that still matters
