Mysteries are hidden in the landscape. History leaves clues. Adventure begins when you start looking.
Follow Emma, Luke, and their grandfather Eli Carson as they investigate the forgotten stories, archaeological mysteries, and unexplained places hidden across Northern California.
Each adventure begins with one of Grandpa Carson’s weathered journals and a mystery he never completely solved.

BOOK ONE
The Obsidian Secret
An ancient artifact. A hidden history. A mystery buried in volcanic stone.
Emma and Luke’s discovery of an obsidian projectile point leads them into the ancient history of Medicine Lake, Indigenous trade networks, archaeology and one of Grandpa Carson’s mysterious journals.

BOOK TWO
The Lava Tube Mystery
Some secrets aren’t buried. They’re hidden underground.
A mysterious entry in Grandpa Carson’s Journal 24 leads Emma and Luke beneath the volcanic landscape of Northern California. Inside a forgotten lava tube, they discover strange markings, evidence that someone was there before them, and an underground chamber that Grandpa kept secret for decades.

BOOK THREE
The Ghost Forest of Gumboot Lake
Not every legend is false. But every legend hides a truth.
When Emma and Luke open Grandpa Carson’s Journal 25, they uncover mysterious clues surrounding the ghost forest of Gumboot Lake. As the water falls, strange creatures, lights, wakes, and markers pointing toward Mount Shasta reveal that the forest may hide more than a legend. But with the secretive Raven Society searching for the same clues, Emma and Luke must uncover what Grandpa discovered before the water rises again.
