A modern-day hunt for Viking treasure collides with Spanish conquistadors and small-town Minnesota in this delightfully zany adventure, perfect for fans of The Goonies and Holes.

Listen. This book is kind of hard to describe. It takes place in a small town called Norse Ridge, Minnesota, which is a lot like any other small town in the Midwest except it has more subterranean caves and people named Olaf. (Also, they eat hotdish, not casserole.) The main character is a kid named Danny Hall, who goes on a hunt with his friends into said caves to find their lost history teacher and maybe a little priceless Viking treasure. Oh, and I'm the narrator, and I'll do my best to keep quiet and just tell the story.

But you should know that this book ALSO includes an evil descendent of a Spanish conquistador and his school principal sidekick who may or may not be up to no good. Also, it has cave pigs, seasick Frenchmen, a sentient rock, a mythological blue moose, and a super epic car chase. It’s a lot to describe in only a few paragraphs—enough to make you go . . . berserk (see what I did there?).

Uff-da! Just open up the book and read it already!
