In the land of Kairos and its many realms, clockwork beasts and automatons live amongst the common, the fantastical, and the evil. Kristane, her brother, and the other adolescents that make up a rogue of thieves have their lives turned upside down by a long-forgotten fairytale, and the hidden truth that lies within it.
An enigmatic figure named, Rellion, cajoles them, and others, to confront and cure the sins of an ancient past. With each beat of the heart and every tick of the clock, the shadowy Forgotten Ones search out the broken heart to give life to the one who wishes to claim a throne...by faith, by curse, by bone.
