The official and international launch of the novel "Marathon" was a luxurious presentation that lasted one hour and fifty minutes. After welcoming and thanking the guests who were given the opportunity to share a literary evening, the host author spoke to us in summary of his work. After his intervention, we gave the space to the Spanish writer and "creator of universes of magical colors" Julio L. Calderón, who read a paragraph of the book that we present. Then, the Puerto Rican writer, poet and international columnist Tania Anaid Ramos González, Azula, presented Wilson's literary profile.
