Found is about a boy named Jonah who is adopted and he has known it all his life. His friend, Chip, just found out that he is adopted too. Both of them are getting mysterious letters from someone unknown. They want to find out what or who is sending these letters. They find who else is getting these letters. Jonah is seeing people just vanishing out of nowhere and wonders if they are time traveling. So they end up going to this camp for adopted children and when they are there, they find out this secret that will change the lives of all the children forever.
My favorite part was when Jonah and Chip found out the big secret because it was very surprising and unexpected. I would recommend this book to people who like unexpected things and mysterious things.
