<s>[INST] This is the introduction to a book about a group of friends at a summer camp. Here is the intro:
"As the sun rises over the tranquil lake, the sounds of summer fill the air. Birds chirp their morning songs, the water laps gently against the shore, and the distant hum of a motorboat can be heard as it makes its way across the lake. The campers of Camp Clearwater, hidden away in the heart of the Adirondacks, are slowly waking up, eager to start a new day filled with adventure and fun. For a group of friends, consisting of 10-year-old twins, Ben and Emma, 11-year-old Jake, and 10-year-old Olivia, this summer is going to be one to remember. They have all been coming to Camp Clearwater for years, and they know its secrets and rituals like the back of their hand. But little do they know, this summer is going to bring some unexpected surprises and challenges that will test their friendship and teamwork in ways they never thought possible."

What do you think the "unexpected surprises and challenges" are going to be?[/INST]
