Cover illustration and design of the book.
Miquel is 11 years old and only expects the 12 to leave his parents to be on Facebook and finally get a room for him alone. But one day, parents at Miquel arrive at home and tell him that his brother, John, is ill: it seems that some relatives have gotten into their blood. In Miquel he does not understand how wild animals are fighting within the body of his younger brother and he is afraid that they also fit within him. With the help of his grandparents, uncles, and parents, Miquel will understand that his brother has cancer and that he is a very important part because everything goes well.
