Caitlyn is a bright, headstrong girl with a twisted past she unconsciously smothers into lost memories. When she is only eleven, she is kidnapped by her father's business rival in hopes of giving up much-needed information. Refusing to talk – and knowing nothing of use – she is placed in the Silver Room, a desperate man's sinister torture chamber, where she meets the monsters who inhabit her nightmares.

A lifetime later, on an innocent summer vacation to her paternal relatives in Romania's notorious province Transylvania, these memories return in a flood when she meets strangers with an aversion to sunlight and bloodstained smiles.

As prisoner to a condemned prince, Caitlyn becomes privy to an underground world where myth and nightmare are all too real, and where at every turn, a new threat emerges.

With dogs waging war and men bent on bloodshed, Caitlyn must team up with the unlikeliest of people to save what is theirs, while standing on the precipice of destruction.
