Why is Trinity special?

Trinity is not just any summer camp. It is specifically geared to kids like Melody who cannot fully enjoy a standard camp because of various medical conditions. As a result, while cabins are shared four to a camper, each camper literally gets their own counselor dedicated just to them. Trinity excitedly announces to Melody’s parents that she is Melody’s camp counselor. She first started coming to the camp to aid her younger sister, but has now returned four years straight to take on the additional responsibilities. Trinity turns out to be a revolutionary figure in Melody’s life.
