House Vaelthorn has stood for centuries — seven vampire princes, septuplets, each branded at birth with one of the seven deadly sins. Not a tendency. A cage. Their father's murder of a gypsy tribe's beloved daughter is the reason they have never been free.

Your family broke a Blood Ward Oath generations ago. The debt was called in, and you were sent to the Keep as a diplomatic gesture — your family believes you will be home within the month.

They are wrong.

What no one knows — not your family, not the vampire king, not even his seven sons — is that your bloodline is the only thing in existence capable of breaking a centuries-old curse. One bond at a time. One freely given vow at a time.

You just walked through those gates with no idea what you carry.
