Although he is just over 30 years old, Carlos Morell (Artés, 1992) has already published half a dozen books. He debuted more than a decade ago with The vapors that kill (Galerada, 2014), which received the Amadeu Oller award, and since then has combined poetry with titles such as Availability (Payés, 2018); the diaries, with Notes for a solo by Scriabin (A Contravent, 2017), and the edition of correspondence such as that of Joan Vinyoli and Eudald Puig (CCG, 2018). Pulse variations (Quaderns Crema, 2025) breaks a seven-year editorial silence, but contains notes written almost a decade ago in which the author reflects on friendship, love, the birth of a literary vocation, and current education.
