In Spain he published his first book of poetic verses "Al Pie de la Alhambra", which was dedicated to the woman who would eventually become his wife, Carmen Rivero.

On February 8, 1912, together with Rosendo Matienzo Cintrón and Manuel Zeno Gandía, he wrote a manifesto which stated that it was time for Puerto Rico to have its independence.

In 1913, Llorens Torres co-founded with Nemesio Canales La Revista de Las Antillas..., a literary publication.
