Since he was a little kid, Zion Coleman has been in and out of Cincinnati Children's Hospital Medical Center because of sickle cell disease. A decade after being born with the condition, Zion has learned how to live with it. He also never forgets how to have fun. One of his favorite times of the year is seeing other kids with cancer or blood diseases at summer camp at Camp Joy, where he gets together with friends who know exactly what he's going through.
