In Billy Richmond and the Upside-Down Stamp Brigade, Young Billy Richmond and his friends stumble upon a vast international conspiracy, kept hidden by a secret society that has long searched for the greatest treasure ever imagined.

It's up to Billy to find the treasure (and the X that marks the spot) before the villains get there first, while also doing his best to avoid camp chaperones, secret caves, mysterious stairways to nowhere, and possibly...bigfoot?

Will Billy and his friends get the treasure before the brigade of evil? They better hope so, or they'll have some explaining to do when their Spring Break camping trip comes to an end!
