The Time Machine / The Invisible Man by H. G. Wells

In a tale of speculative fiction, a brilliant scientist invents a device that allows him to travel through time, leading him to witness the distant future where humanity has evolved into two distinct species: the gentle Eloi and the subterranean Morlocks. As he navigates this new world, he grapples with the implications of time travel and the fate of human civilization. In a separate narrative, a gifted but misguided scientist discovers the secret to invisibility, only to find himself consumed by paranoia and isolation as his newfound power spirals out of control, ultimately leading to his tragic downfall.
