The nature of time has forever perplexed humankind. Add the many ripe paradoxes of time travel and the situation gets complicated. While science has shown us that time travel is technically possible, at least on paper, we still know little about what time actually is, or our place within it. Science fiction has long explored this theme and it has become one of the cornerstones of the genre. In this collection of stories, we find visions of what time travel could be, what could go wrong, and dive headlong into the paradoxical nature of what it might entail. Tales ranging from 1942 to 1960 bring us into these mysterious worlds and provide a window into what the writers of this era grappled with when exploring time and the possibilities of traveling within the fourth dimension. Readers will also delight in traversing another time in literature, with stories that first appeared in Worlds of IF, Astonishing Stories, Galaxy Magazine, Thrilling Wonder Stories, Startling Stories, and Imagination Stories of Fantasy & Science Fiction.
