After experiencing pain in his hip after going for a jog, 14-year-old Zach Sobiech did what most teens do, and saw a physical therapist for treatment. But the pain kept getting worse, so he went in for more extensive tests and found out that he had a rare form of bone cancer. Now, at 17, Zach's had many rounds of surgery and chemotherapy, but devastatingly, nothing's helped destroy his Osteosarcoma.

Doctors estimate the Lakeland, Minnesota, teen only has a few months to live, but Zach's decided to embrace every day with hope and joy. He's funneled that outlook into music and has written, performed, and recorded a tune called Clouds, which is his goodbye song to family and friends.
