- Description from Novelupdates

A man was about to commit suicide and decided to search for a way to die on the internet, but then he found an odd site that asked a lot of questions and had a point based system that allows you to create skills for a character. He took interest in it, and when he was done setting his character, he was asked, “You will now be transported to a world with the settings you chose. Coming back is not possible. Do you still accept?” Without thinking much of it, he pressed YES and found himself in another world with the skills he chose to have.

He is back! This time fiercer, faster and stronger, with only one thing in mind. Revenge!

Prince of Darkness, Son of the Devil, Lucian is back and he has only one thing on his mind. Revenge! That's until he meets her. A woman who entices him beyond reason, but who also claims to be his wife. Surrounded by dark secrets and powerful enemies Lucian must decide who to trust and who to destroy.

Can she protect her heart from the man whose touch sets her body aflame? Or will she surrender to her desire and risk her heart once again?
