Our King's Deadly Sin

Anastasia Brown. A fierce yet careless young lady. All alone in a world of cruelty. Surrounded by enemies with no one to trust.
Ethan Dmitri Petrov. An introverted demon billionaire with a dark past and a wounded soul. Although looking perfect on the outside, it was impossible to weigh the kind of pain Ethan held inside him. Soothed by an imaginary female he began to write letters to 200 years ago, he was able to survive through the world of war and the numerous innocent blood he had shed. Somehow, 200 years later the letters get to Anastasia who seem to not give a care in the world but things start to change the moment Ana becomes moved by the romance and pain passed through words and starts to write back to a man she is not aware of.
With another war lurking around, unexpected people plotting deceit and Ethans unacceptable sin of the time he was known as Dmitri, is there a silver lining for them, or is there life meant to be hell on earth?
Will Ana be his rescue or would she be his arrest?

Ethan was left speechless.
