Book: A Revolutionary Adventure

Join Mattie and Josh, the sister-brother team who discover the mysterious Chaos Cave. Ghostly breezes chill their spines as they try to interpret strange petro glyphs and a note of warning. The kids stumble upon a skeleton whose bones rest around an ancient Chinese Puzzle Box. Inside the box they find a ring–a ring that will change their lives forever.
Chaos Cave transports Mattie and Josh on A Revolutionary Adventure as the kids travel through time to Boston, 1775. They encounter the evil Archie, who murdered his own brother and now seeks the ring for all the power it holds. While they desperately try to evade Archie, they must also find a way to return safely to their own time without altering the course of important historic events.
