If you create exciting conflict within the group, the story will intrigue the reader and pull them into the story.
Yes, great advice, Chloe! Stories usually have a conflict, and they also usually have some sort of "love interest." Someone who is in love with someone. I guess that is the sort of story people like to read.
So... what is the conflict? Is it a natural disaster? A terrorist attack? Let your imagination carry you. I look forward to seeing what you write about!
