Warning! Unfold this book for scary dinosaur surprises!

Two brothers set off on a pretend expedition to find dinosaurs. Of course, everyone knows dinosaurs don't exist, so there's no need to be scared--or is there? The brothers see rocks and mountains, but as each page unfolds the landscape reveals itself full of dinosaurs!

In his signature bold, sparkling style, renowned author and illustrator Mark Janssen plays visual tricks with scale. Proceed with caution and look closer...that tree or hill might be a dinosaur, too.
