Title: Passage Finder by Thomas Ask
Get ready to fly, sail, camp and discover! This is a fast-paced Christian-themed scientific journey of exploration filled with technical discovery and building, as a beloved father and son grow in their Christian faith and make a surprising discovery underneath the Earth. ~ CBM Christian Book Reviews
David and son, Aaron, work together in this exciting exploration of earth and sea as a father and son duo filled with comradery, showcasing faith and trust in Jesus. Their adventures take them across the globe, and both admit that they love exploration, especially David. Exciting, the two find different landscapes traversing across sea and land in their exploits. Questions have arisen from a mysterious island sinking near Heard Island. Lessons range from oceanography, Earth Science to sailing emerge, as they discover circular chasms on the sea floor under the deep waters surrounding the island. Aaron’s search has begun. Why did that island just disappear and sink, and why so violently? Aaron had barely escaped.
Yet, despite their commonalities as father and son, their Christian faith keeps them going. Witty and filled with vivid writing and an understanding of how the world works, the author slides in tidbits of life lessons from the Bible. The freedom between these two is refreshing and will leave one yearning for travel and adventure. Building and designing ideas seem to flow between them, passed down from the previous generation. With a taste for adventure, readers will enjoy scenery changes from sea planes to a luxurious jet. Their journeys take them farther than they could have imagined.
From the southern ocean, over the Atlantic to Africa, notably Zanzibar, with a pitstop in Madagascar before an Antarctic expedition. Then both are off again – this time to the jungles of South America. The two travelers begin to answer questions as to the reason why that island sank; this leads them to Canada. The untouched Artic tundra to be exact.
The Gospel message and salvation is intertwined within the book. Meanwhile their Christian faith brings hope. David teaches his son lessons, deep lessons about love, God’s creation and why God had to allow evil. These are much appreciated answers without complicated theology. The way David answers just makes sense.
This is a wholesome adventure recommended for young boys and girls above the age of twelve and comes highly recommended as a scientific, Earth-Science and Christian-based novel that gives the desire to explore different places throughout the world. One might even have a map handy, as these two travel quite extensively.
A wonderfully written novel that never left me with a dull moment. I felt as if I had travelled right there with father and son. A well-done book fit for family entertainment!

Excerpt from River Finder
Their peaceful river had rushed into battle. The river rose upward—tearing itself free of gravity’s downward grip. It was being pushed up by an opposing river that battled to win a war that never would end. A tall standing wave was formed by the two giants of the jungle. Woken like sleeping lions, the rivers raged at each other, soberly provoked. The clashing waters pushed up a giant upside-down waterfall hundreds of feet into the air.
As the river rose, it stripped itself of brown jungle mud and replaced it with white roaring armor of frothing sheets of water. Veins of serpentine water drove down and into the uprising flow. It only fell back to Earth when its energy completely withered. But even then, the river’s brown water kept its white plume as it plummeted down and disappeared.
Overwhelmed, they beached the raft. They grabbed machetes and quickly climbed up the hill alongside the upside-down waterfall. They climbed up and up, but the upswelling water continued above them. When they got to the top of the hill, the upside-down waterfall still towered above them. They were now at the edge of a giant ring of cliffs that joined in with a steep mountain valley opposite them. The wind blew fiercely and they could feel the water mist from the twisting, raging waterfall penetrate their clothes.
Now free of the jungle canopy, their eyes adjusted to the unrestrained and distant views. They looked down into the deep valley below them. Its dense vegetation was dominated by a huge river rushing through the valley and in the opposite direction of their river. The two rivers smashed together with full force. The collision of rivers was producing this rising standing wave of water that towered above them. They stood with heads arched back and watched the upside-down waterfall flying high in the air as the twisting strands of separate streams snaked downward around the mass of rising water.
“Amazing!” David yelled over the noise.
