World Lines by EB Diamond is a science fiction adventure with the restless mind of a thought experiment and the voice of someone telling you an increasingly strange story across the kitchen table. At its center is Professor Nathan Sloan, a physicist whose fascination with space-time becomes a deeply personal quest to understand what happens when a human “world line” refuses to behave normally. His theory suggests that certain people, known as Alternates, can cross time, space, and dimensions along unusual paths, turning ideas like ghosts, prophecy, disappearance, and even immortality into problems that might be plotted on a graph. Around that premise, Diamond builds an adventure involving ancient Egypt, a neutrino mine in Newfoundland, a missing graduate student, an Air Force pilot in North Africa, a mysterious emerald ring, an eccentric businessman, a shape-shifting mathematician, and RCR23, a decidedly peculiar robot who becomes one of the story’s most important links between realities.

I think what gives the novel its personality is the way Diamond mixes serious scientific curiosity with absurdity, wordplay, literary references, and a narrator who’s perfectly willing to interrupt the proceedings. Physics and metaphysics bump into Alice in Wonderland, The Wizard of Oz, Moby-Dick, fairy tales, religion, archaeology, computer technology, and jokes about the habits of scientists. TD1 and TD2 can argue about invisible particles or a fisherman’s “magnetic pole” while the fate of civilization hangs somewhere in the background. Marco Spelling can worry about turning a profit from a disaster-prediction business while realizing that a successful prediction might leave nobody around to collect the money. That humor isn’t decoration. It’s part of the book’s way of thinking. Diamond repeatedly follows logic until it circles back on itself, becomes ridiculous, and then unexpectedly raises a question worth considering. The result is a novel that feels curious, playful, argumentative, and cheerfully unwilling to stay inside a single genre.

Beneath all that intellectual play is a surprisingly human story about people trying to recover what they’ve lost. Sloan’s obsession reaches back to the death of his wife, Jean, and his discovery of an impossibly modern ring in an ancient setting. His daughter Darien, tough, impatient, resourceful, and fiercely loyal, takes up the search when Richard Watson disappears during Sloan’s experiment. Andrew McBarrister, the enigmatic Alternate who appears in different identities and different moments, gives the novel another emotional thread as protector, observer, mathematician, and Fisherman. The characters keep asking scientific questions, but many of the questions underneath them are painfully ordinary: Where did someone we love go? Can we reach them again? Does death represent an ending, a transition, or simply a point we can’t see beyond? That emotional current gives weight to a story filled with cosmic forces and multidimensional speculation. The apocalypse may provide the scale, but mortality provides the stakes.

By the end, World Lines brings its scientists, soldiers, Alternates, skeptics, believers, and competing explanations together at the Newfoundland mountain, where the abstract questions become immediate and physical. The conclusion is eerie, sad, strange, and fittingly circular. Diamond doesn’t turn the book into an answer key. The novel remains committed to uncertainty, leaving the reader to decide how much has been proved, how much has been imagined, and whether those categories were ever as separate as we thought. That openness feels entirely appropriate for a book so interested in the boundaries between science and faith, life and death, reality and story, and one moment in time and another. World Lines invites you to look at a straight line, wonder where else it might lead, and entertain the possibility that an ending is simply the point where our view runs out. World Lines turns the mysteries of time, death, and the universe into a funny, imaginative adventure that leaves you wondering whether the impossible is simply reality seen from the wrong dimension.
