Rex Ryder and the Lost Dinosaurs
A Rex Ryder Adventure
Some discoveries change history. Others should remain hidden forever.
When fourteen-year-old explorer Rex Ryder joins a scientific expedition into an isolated volcanic valley, he expects to uncover evidence of a forgotten civilization.
He never expects to find living dinosaurs.
Hidden beneath towering rainforest lies a lost world untouched for thousands of years. Ancient roads disappear beneath jungle vines. A mysterious observatory watches over an active volcano. Strange footprints appear where none should exist.
Then Rex sees them.
Not fossils.
Not bones.
Dinosaurs.
Living, hunting, raising their young exactly as they have for millions of years.
But the valley is changing.
The mountain is awakening.
As earthquakes shake the ancient landscape and an eruption threatens everything inside the crater, Rex and his team must survive one of the most dangerous environments on Earth while making an impossible decision.
Should the greatest discovery in human history be shared with the world...
...or protected forever?
Because some secrets are worth more than fame.
Some discoveries were never meant to belong to us.

"Some Discoveries Were Never Meant to Be Made"
"Rex Ryder is a hero young readers will follow anywhere — even three miles beneath the Pacific into an ancient city that shouldn't exist. The pacing is relentless, the deep-sea setting is genuinely atmospheric, and the mystery of what's waiting in the darkness delivers exactly the spine-tingling dread promised. Science, survival, and lost civilization mystery woven together brilliantly. A series debut that earns every comparison to Percy Jackson and then some."
