Jacob van Willingen arrives in a remote Romanian village aiming for a short visit. A member of the highly secretive Society for Psychical Research, Jacob has been charged with exterminating Caleb Donnithorn--but the society's intelligence about the reclusive nobleman is less than complete. As he studies his target, Van Willingen is drawn to Donnithorn, enthralled with the nobleman's alluring brides, three of society's most luminous geniuses gathered from the corners of Europe to create a fantastical machine: a resurrection engine that can capture a human soul at the moment of death. Caleb Donnithorn represents everything that is evil in the world, but there is more to him than is initially apparent. What he knows about van Willingen is a truth so shocking it will shake the young scholar's world to its very foundations. Cast out from his friends and his beloved Society of Psychical Research, Jacob van Willingen will jettison everything he holds dear to remain with one whose love commands the highest price of all.
