The prequel and sequel to the short story "A Bag For Life" from Scholastic (Don't judge me this was an English project and I'd like to share it)

Iris is a shy kid who one day gets lucky by playing and winning a almost impossible survival game but then she start worrying about her and one friend can go to the camp but little did many people know that this newly discovered island (that was discovered five months ago) is full of mystery. (By the way the introduction will be a bit short)
