La soledad de los números primos

When her father forces her to attend a ski school, Alice suffers a serious accident that will mark her forever. In turn, Mattia, a reserved child, bears the fatal consequences of an act he committed a short time ago. Childhood has caused Alice and Mattia those kinds of wounds that are difficult to heal, and which lead them to devastating loneliness during their adolescence. However, the moment the two meet, friendship will be born and their lives will intersect several times; At times, they will feel closely united. Alice will dedicate herself to photography, and Mattia will develop his talent for mathematics. And yet, like those special numbers known as "twin cousins", something keeps them hopelessly "lonely and lost, together but not close enough to really touch", as Mattia thinks.
