What happends in the end of book looking for JJ?

In the end of "Looking for JJ," JJ is found. He's not dead, as feared, but he's severely traumatized and in a very fragile state. While the exact details of his discovery and his condition aren't explicitly spelled out, the overall message is that he's alive, but his recovery will be a long and difficult process. The book focuses more on the impact of the experience on those searching for him and the emotional resolution they find. There's not a neat, tied-up bow, reflecting the complexity of real-life trauma and healing.
