After Ceres, Janet van den Brand and Timothy Wennekes once again immerse themselves in the world of teenagers. In a Dutch suburb, they meet two brothers, Daan and Sam. The boys are dealing with things that kids their age shouldn't be concerned about. Daan has a connective tissue disease called EDS, which prevents him from doing things that other kids can, while Sam struggles with his identity because he used to be a girl named Mara. The brothers support each other, but when Daan starts high school, his world becomes a lot bigger. At the same time, he struggles with the limitations imposed by his illness. He ends up in a roller coaster of feelings and learns things about himself that he didn't know existed.
