Casper never imagined that finding a glowing compass in his grandfather’s attic would lead him into a world where memories could be stolen, cities floated on clouds, and the fate of two realms rested in his uncertain hands. When the compass activates during a thunderstorm, he’s pulled into Aethermoor, a land where forgotten dreams take physical form and where a sinister force called the Hollow is consuming everything in its path. Armed with nothing but his wit, the mysterious compass, and an unlikely band of companions, Casper must navigate treacherous skies, face his deepest fears, and make an impossible choice that will determine not just his future, but the survival of both his world and the one he never knew existed.
