Author: José Pablo Iriarte
Published in: Fantastic Stories of the Imagination, February 2015 (Issue 225)
Description, by Nicky Magas [Tangent]: "Mark would do anything for his eight year-old son Jason in José Pablo Iriarte’s “Weight of the World.” Even leaving with his wife and son to take the eight-day journey back to Earth from their home on the moon is nothing if the treatment of Jason’s aggressive cancer is successful. But the prognosis is grim and Mark must struggle with his own emotions to put on a positive face for Jason. The weight of the world is pressing down on Mark and his family—literally—and the responsibility of being optimistic for all three of them is starting to take its toll."
