Young Quinn Campbell's greatest worries are pleasing his doting uncle, placating his fussy aunt, and doing his best to keep the quiet, brooding Agatha-a ward to his family and his best friend-happy and safe.
But Quinn's active London life is suddenly spun sideways by a chance encounter with a shadowy figure in Brompton Cemetery.
With the speed of a gunshot, Quinn and Agatha are kidnapped.
So begins a treacherous and bone-chilling journey through the darkest parts of 1800's Europe, led by a tall, eerie and irascible captor whose motives are shady at best, whilst being pursued by factions whose intents may in fact be deadly. And along the way, Quinn might just learn a few secrets about himself-and his traveling companions-that will change him forever.
