LIGHTSPEED is a digital science fiction and fantasy magazine. In its pages, you will find science fiction: from near-future, sociological soft SF, to far-future, star-spanning hard SF-and fantasy: from epic fantasy, sword-and-sorcery, and contemporary urban tales, to magical realism, science-fantasy, and folktales. Welcome to issue 167 of LIGHTSPEED! Our science fiction section kicks off with a bang with Endria Isa Richardson's new SF short story "A Pedra," which explores the difficult topic of human experimentation. Susan Palwick turns her attention to the effects of climate change in her story "Mother's Day, After Everything." David Anaxagoras and Rich Larson bring a little levity with their flash pieces, "Under a Star, Bright as Morning" and "Limping Toward Sunrise" (respectively). Our original fantasy work includes "How to Know Your Father Is a God" by Modupeoluwa Shelle. We also have a novelette by Vandana Singh-"Travelers' Tales from the Ends of the World"-that powerfully explores the impact of climate change through a magical lens. We also have a flash story ("Salemo") from David Marino, and another ("a testament to indirection, an enigma, the sun above") from Mitchell Shanklin.
