The British youth fiction writer Jenny Valentine is touring the world to talk to teenagers in various countries to find out what matters most to them. Fernando “Nando” López is a novelist, playwright and author of several works of children’s and young adult fiction, including Los nombres del fuego and La edad de la ira. His play #malditos16 examines suicide, anorexia and self-harm, and is inspired by his work as a volunteer at a hospital, where he runs literary workshops with teenagers who have tried to take their own lives. Both will talk to the publisher and writer Carlos Sánchez Lozano about worrying, the imagination and what it means to be a teenager in the 21^st century.
