Book 1: BLUE JOHN'S CAVERN
Traveling through caves, jumping through time.
Nothing interesting ever happens in Diamond Falls, West Virginia, and that's doubly true for local teenagers Emma and Brody. Little do they know that their neighbor, a famous geologist, is about to show them the wildest time of their lives.
When Mr. M's prized rock and mineral collection is destroyed before it can be displayed at the state museum, Emma and Brody jump at the chance to find new samples. The geologist accepts the offer, and promptly sends them back to the year 1775 to help!
Back in time and across the pond in Derbyshire, England, Emma and Brody team with a mysterious young girl named Max to recover one of the rarest minerals in the world: Blue John Fluorite. Tapping into courage they never knew they had, the formerly ordinary West Virginians must protect a cave, avoid gun-toting soldiers, and return to the present before they're trapped forever.
Book 2: RUSHER'S GOLD
A time traveling cave. A vicious band of miners…and pure gold.
After a successful trip to 1775 England where they collected the rare Blue John Fluorite, Emma and Brody are quick to jump at the chance to travel to the California Gold Rush in 1851. When they arrive at the Gold Rush and meet an old acquaintance, they think the mission will be easy until they realize their friend may not be able to help them at all.
When their actions in the past erase their future, can Emma and Brody right the wrong? With a hostile group of miners hot on their trail, Brody and Emma must collect the gold, save their friends, and salvage the future before it is too late.

When their attempts to collect the perfect opal anger the locals, the kids flee and accidentally land over 2000 years in the future in South Carolina. Can the kids figure out how to return to their own state and time? Will Rose's secret stop them from helping Mr. M? Will Max finally figure out who destroyed her Grandfather's prized rock and mineral collection and why? The answers are all inside but may leave you with a new mystery to solve.
