Established in 2010 in Badajoz, Extremadura the independent Spanish publishing house Aristas Martínez declares that it exists for both readers and booksellers, avoiding classification by genres by delving into the boundary between fiction and non-fiction. It traces editorial lines and poses challenges to its authors in placing difficult projects. These include works by Javier Calvo, Jorge Carrión, Laura Fernández, and Colectivo Juan de Madre.
