I Married The Devils King

Zak's life is pretty ok. He goes to a good school, lives with his dad, and goes to see his mom and sister on the weekends and half of breaks. But there's a twist to his family, his mother is religious and believes in god, while his dad isn't and can summon demons. This was one of the reasons his parents are divorced.

But what happens when his father goes to far with summoning a demon and Zak is kidnapped by said demon.

Can't really say anything but it gets crazy.
