The Greatest Treasure Hunt - 9 (Paperback original)

Rappel out of helicopters, off-road along the Baltic coast, and smile for the camera! It's all in a day's work for the Collier kids!

Wait-what?

The Kidd siblings have rescued some of the world's greatest treasure, without ever seeking fame and glory. So they aren't happy when the Collier kids start treasure hunting for the camera, more focused on looking good and selling ads than actually recovering treasure. When the Kidds are invited to compete with the Colliers for the title of 'The World's Greatest Treasure Hunting Kids,' they jump at the chance to show the world real treasure hunting.

But with rumors swirling of a mistake made by the Kidds' great-grandfather years ago, the Kidds discover that fame and glory aren't the only things on the line. Will they be able to solve the mystery, restore their family name, and recover their biggest treasure haul yet?
