In Chaos Cave: A Revolutionary Adventure, author Lesley Downie tells the story of Mattie and Josh, siblings who travel through time and use GIS maps to secure victory in the Revolutionary War.

When the kids explore a mysterious cave, they are transported to 1775 Boston. In a quest to return home to their dad, a GIS expert, they join forces with famous patriots and witness first-hand the days leading up to Revolutionary War. By using their laptop computer and GIS maps, the kids are instrumental in American triumph. But, Mattie and Josh must solve the mystery of the skeleton, the puzzle box, and the ring in time to return home before war breaks out.

“The unique blend of historical fantasy and modern GIS technology make Chaos Cave: A Revolutionary Adventure both educational and interesting, but it is Downie’s skillful writing, artful pacing and the humanity of her characters that make the novel fun and captivating,” said Mark Stewart, a GIS educator. “This is definitely a story that deserves a whole series!”
