Fantasy, Magical Realism || The late Julio Cortázar was a sickly child and spent many hours in bed. Perhaps those memories inspired "Cefalea," the feverish story of the care and feeding of fantastical creatures called the mancuspias, which debuted in his 1951 collection Bestiario. Tor.com is proud to share with you "Headache," the first ever English translation of "Cefalea."
