 Hi, I read a book in 2017 that was a summer reading book back in highschool. I don’t remember so much about it but I’ll say what I remember. It was a young adult book.
The book started off with these group of kids in a lighthouse, these teenagers did criminal acts and our main character, male, stole a bike so he was put their as another option of juvenile detention. Between the middle of the book he’s driving a car with this other kid with him, also male, off to a beach where they could make a bonfire and eat the food they’ve stolen. Our main character went to set up the bonfire while his friend went out to look at the ocean, only to turn back to ask what he wished to eat and see the guy gone. Following the footsteps that lead straight into the ocean, he knew his friend died walking into the vast cold sea at night as he had problems with his will to live.
