As of my knowledge cutoff date in March 2023, I do not have information on an author named Isa Arsén. It is possible that Isa Arsén may be an emerging author, uses a pseudonym, or is known primarily in a specific literary or language community that has not gained widespread recognition in mainstream English-language literature. Alternatively, there might have been a spelling mistake or a different transcription of the name. If Isa Arsén has come to prominence or recognition after my last update, I would not have the information available. Please check the latest sources or provide additional details, so I can try to assist you further.
