Only Chance

Contains hiccstrid and dragons. Based after the events of How to Train Your Dragon 2.
'When you think that it's all over but the past comes back bigger than ever. Hiccup and Astrid are in grave danger. Hiccup is just getting used to becoming chief, however with new discoveries and hard desicions to make, did he overestimate how safe he and his tribe were. And now he needs to deal with things that he and Astrid are very much involved in. Will they make it out alive? Who will they have to face to win? Will he lose the girl he loves most in the process?'
This is my very first fanfic so I'm hoping that I will do a good job and not make any spelling errors. This does contain Hiccstrid and much more hopefully interesting stuff.
