Winnie, a graduate student in folklore, breaks into the forbidden Vantro Castle in Eastern Europe to complete her thesis.
On a stormy night, she meets Karen, an immortal prince with neither a shadow nor a reflection.
The Blood Embrace, a blood pact, a life-or-death bond: she becomes the only vessel capable of freeing him from a thousand-year curse of sunlight.
His obsessive possessiveness gradually turns to genuine love, but danger is closing in: a duke coveting the throne, hunters sworn to avenge their ancestors, and the truth behind a blood pact buried for a thousand years…
He says, “I’ve lived for three thousand two hundred years, and I’ve never regretted making this blood pact with you.”
She says, “I won’t break the blood pact. I’ll bear this curse with you, and we’ll stay together for eternity.”
After a thousand years of endless night, at last, they have a day to look forward to, because they have each other.
