La tana del bianconiglio

In a gray world, Henry created colors. He managed to trap them inside small glass balls to give to his sick wife, but he couldn't save her. From that day on, he began to produce colored balls non-stop, involving his four sons but refusing to share that incredible magic with the rest of the world and arguing with his youngest son, Stick, about it. Twenty years later, Stick returns home because his father is dying. The only hope seems to lie in a very expensive medical device, but only by freeing the color from the glass balls will Stick and Henry be able to reconcile and fill everyone's lives with beauty.
