Flashlight Adventures: Into the Depths of the Earth

Taskulamppuseikkailu: Maan uumeniin

Turn on your flashlight and let the adventures begin!

Jungle vehicle Kaldera embarks upon an underground adventure when Luttinen follows his nose and heads into the depths of an abandoned mine. The journey continues into a cave and becomes more and more dangerous along the way. How will Kaldera’s crew survive as red-hot lava bubbles in the depths of the cave and their torch starts to run out of battery?

Into the Depths of the Earth continues the popular Flashlight Adventure series. When you put a flashlight behind the book’s pages, its hidden pictures start to mysteriously glow. A flashlight will reveal secrets from the depths of the earth, which propel the exciting expedition forwards.

The Flashlight Adventures series will include one new book release per year. Upcoming stories will see our fearless explorers perform an archaeological excavation, conduct a mountain rescue operation and explore a city’s underground tunnels during a major power cut. Although their stories are fictional, these books are factually accurate and perfect for any 4-8 year-old with a curious mind!
