Love is a Battle Jack X Hiccup

Sorry I had to use art for the cover and not mine. I'll change it when I can. Anyway here is the story.

STORY
Jack washes up on Berk. A place where gay's, lesbian, etc is not welcome. They are murdered. After Hiccup and Jack start dating Jack is murdered and everyone wants to know who his boyfriend is. Can Jack save Hiccup or will Hiccup be murdered as well?

Also Hiccup and Snotlout are cousins so Snotlout can also become chief.
