Dear Diary,
Guess what? We’re sitting with hundreds of people waiting for the world’s most famous geyser, Old Faithful, to erupt. I can’t wait to see it . . .

Join the Parkers, an intrepid family of four, as they explore the wonders of America’s first national park, Yellowstone. Twins Morgan and James marvel over the geysers, thermal pools, and vast array of wildlife. But when they come face to face with a grizzly, what will they do?

Each book in the exciting Adventures with the Parkers series for kids 8–13 explores a popular national park and is packed with adventure as well as engaging and educational facts about nature, outdoor safety, and much more. Vacation has never been this fun!
