Mike and Kate are in Denver Colorado for the Colorado Rockies’ Opening Day. BUT IT’S SNOWING!

But when the ballpark engineers get a mysterious note saying that someone may tamper with the scoreboard, the snow becomes the least of the cousins’ problems. It’s time for Mike and Kate to switch into sleuth mode and solve a mystery that will take them underground, a mile above sea level, and even face to face with a dinosaur!
